It has the STD micro B USB, having invested a lot in micro B USB cables at home and in the cars, and having about 10 devices (between all family members)using this type of connection at home, I did not wanted to bring a new plug-in adapter incompatible with the rest that I have; don take me wrong a believe the new micro USB-C to be great, but I will wait a couple of years until becomes the true standard in the industry and I have no choice but to adopt it.

32/2GB it’s enough for me for the next couple of years, I do a lot of reading, and play few light games with it, and I considered the tablet to be fast and responsive for what I do with it. I do not have a tendency to overload my devices with useless applications, which I hardly use.
For any device phone or tablet that you buy today, seriously consider your minimum specs to be 16GB/2GB for a light user and a minimum of 16GB micro SD, or for a medium user 32GB/2GB with a micro SD 32GBif you need more storage. Avoid 8GB /1GB ram it’s already too small, and you are wasting your money.

The tablet screen aspect ratio is excellent for reading, and it is light weight, some reviewers have pointed out that the screen may be dim under certain conditions or the appearance of a yellowish color when the brightness is set too low. It took me a couple of days to get accustom to it, but I realized that the soft tone is great for reading white pages at night with the lights off.

Price, after buying several expensive ($400 +) tablets and phones during the past years, I came to the conclusion that it was better to buy devices in the $200-$250 range, may be $300 max in some cases; technology, firmware and apps are constantly changing, and after a couple of years I ended with an old expensive device that lagged in all aspects. It is better to keep the price difference in your pocket, and change more often the devices. (But definitely I stay away from cheap low specs unknown brands devices; it is just throwing away money, avoid $100-$150 Phones or tables)

ASUS apps, yes there are a lot of them in it, but I can easily turn them off, as some of the Google apps that I do not use. Since I have different brand name devices, I decided to use Google apps as much as possible, so there is a better synchronization and standardization across all devices that we own at home.

As for the launcher I am using the Nova Launcher in all devices, the main advantages of this launcher is that I can back up the screen/desktop settings , resize the icons, icons letter size, and I am able to lock the desktop so no one can move or delete the icons as they are set on the screen. I highly recommend you the Nova Launcher.

Asus launcher UI, there is something good for those who are not technically inclined, and a standard AndroidUI maybe overwhelming. Asus provides with the choice Asus Easy Mode which is a simplified UI / Launcher, it is built-in in new Asus phones and tablets, but is is also available as a standalone app [...]
The link for the manual is below, in case you want to read about it.

Speaker sound quality and microphone is good for a Skype or Viber conversation, clear no noises, good for watching a YouTube video, as for music get a decent pair of headphones.

Two cameras, front and back, no flash. I do not talk much about a cameras in any tablet, for me are just an emergency camera, I prefer to use the one on my phone, it is very uncomfortableto take a picture with a tablet, which may end on the floor. So how many mega pixels and so on, you can check the specs, the only thing relevant for me in that department, is that it has a decent front and back camera for web call Skype or Viber. In case you ask the back camera is good for web calls, for example during a web call you want to show someone an item that you just bought. That is the reason for the 2 MP Front Camera andthe 5 MP Rear Camera, there is no need for a million MP camera on a tablet.

Why not a Samsung?, I have bought over 7 Samsung devices, they are great quality devices, but I got tired of the physical home button, the touchwiz, and the lack of updates, if you check in Amazon you will see that most of the 8 Samsung tablets still running android 4.4, and in my personal experience, I doubt that they will ever get to android 5, while android 6 is already on the market. Also of those Samsung 8 tablets that compare in price to the Assus, the Samsung have lower memory specs (ram and storage).
Then Samsung has a million different SKU / models for the same device, to a point that it becomes hard work to find which is the most recent / newest product , and to compare specs, and prices. I believe that if a manufacturer wants to confuse me with their product offering, I better skip them. ( I may end with an older discontinued item, with little or none tech support)
So for those reasons, at the present time I decided to pass on Samsung devices.

I hope you find my review helpful, Do you have a questions?let me know.

Update October 16, 2015
Connecting to weak WiFi signals
If you are trying to connect to a weak WiFi (you are far from the router) here is 3 things that you need to do
The tablet has better reception in portrait and landscape with the power and volume buttons facing down
Turn off power saving
Settings>WiFi>3dots menu>advanced>keep WiFi on during sleep>always

The battery will last less, but you have good chances of getting that weak signal. Remember to change back the settings, if you no longer need it.

Update September, 2016
Marshmallow Android 6 is available as a manual update, which requires you to download the firmware, and install it to the root directory, no OTA available.
link Asus [...]
Updates are available for Z580C for the (Z580CA look for the appropiate support link)

Update October 29, 2015
The tablet received a minor OTA update, still 5.0 android (total of 2 OTA updates, since I bought it)
Pay attention to this, the right way of holding the tablet in Landscape mode is with the power and volume buttons facing down. (you will get full wifi bars)
Also, the volume display on the screen will move/agree according to pressing + or - volume buttons.

Hardware:
I opted for the budget friendly 2gb/32gb model because I didn't think the additional RAM would benefit me and I just don't need 64gb storage. I don't take pictures with a tablet so the 5mp/8mp cameras of the Z580CA wasn't attractive either. I wasn't aware until after I purchased the Z580C that the Z580CA model's CPU is 2.3ghz compared the 2gb/32gb model's 1.3ghz. That additional processor power might've been enough to push me into that model had I not already received, setup, and enjoyed the Z580C so far.

Performance:
The Z580C is pretty peppy. Applications open and close quickly, webpages scroll smoothly and zippily, and after playing Asphalt for ten minutes I'm pretty satisfied. I also played some Words with Friends and Solitaire and that went super well too. I'm also pleased with wifi so far (in comparison to my Nexus 7).

Pros:
The obvious pros are the great price, 64bit quad core CPU, 32gb storage expandable to 128gb, 2gb memory, 2k screen, left & right front facing speakers, and light weight. It's 1.5 ounces lighter than my Nexus 7, a little taller and wider while significantly thinner. You can feel the 1.5 ounce difference. The 4:3 aspect ratio is awesome. I know it's nothing new in tablets, but it makes a world of difference browsing web pages in portrait. I love it.

Cons:
The main negatives I hear about the Zenpad S is the screen dimming on its own and the poor sound quality. It does dim automatically on some applications but going into the power management section and turning off power save functions and then manually setting the screen brightness has worked around this for me. Maybe Asus will fix this in a software update soon.
Regarding the speaker quality. This is a 10.6oz., 6.9mm thick tablet-how people expect booming bass and bright highs puzzles me. The speakers are fine and they point at your face. They are good.
I've also heard people complain about the power button being stiff. Yah, it's a relatively stiff press but it's still effortless. And with the tactile soft click you know when you've done it right. It's a non-issue. Plus, I really like and prefer to double tap on the screen to wake up the tablet instead. Another cool feature.

OS:
Coming from a Google device with the unmolested Android OS I was wondering how the "Zen UI" version of Lollipop Asus installed would be and the truth is, it's fine. It took a couple minutes to get used to. Within minutes I had a new launcher and everything setup how I want.

Aesthetics:
One thing I thought would bug me was the Pick-Up-Stix counter style "brushed aluminum" backing but, in hand, it just looks black. At specific angles you can see the cross hatch pattern but it feels nice and is fingerprint proof. This doesn't matter at all really but the back of this tablet looks really nice. The slim polished edge of the aluminum backing that separates the Pick-Up-Stix counter style brushed aluminum from the leather-look plastic is beautiful. The branding on the leather-look plastic is very subdued which I like. This tablet really looks great.

Overall I have to say, as everyone will say, the Z580C is a very good value. Is the Z580CA a better value? I don't know I don't have one. If this one came with a longer power cord I'd give it 4.5 stars so I want to give it 4.49 stars but I can't. So I rounded.

9/3/15 - After a couple weeks with this tablet the excitement has definitely settled down...a lot. There've been several ASUS updates, one to the ASUS's side of the OS I think (still L5.0), and many to all of the ASUS installed applications. The tablet is noticeably less zippy. It's not a sloth or anything, but it makes we wonder if I really should have waited a couple weeks for the Z580CA version instead with it's increased processor, memory, and gpu power.

The screen dimming thing seems to have subsided through the updates...I think. I realized today I haven't noticed it happening for a couple days other than going from a bright area to a dark area which is normal. The only thing that's a little weird still is the ASUS vivid picture maker brighterer doodad. I notice it very rarely, but sometimes when I open an application that's colorful, like Words with Friends, the colors are super hot and washed out looking for a few seconds then corrects itself.

Battery life has been average. I charge it every day-day and a half. I use it for for a few hours a day to stream videos, plays mediocre games, check email, and surf the information super highway.

I still think it's it's fantastic bargain and have no real major complaints about it.

After almost two months I still enjoy this tablet. Some things of note after more use: I really like whatever coating is on the screen. My Nexus7 would be covered in fingerprints and swipe marks after several days but this screen stays relatively clean except for single fingerprint marks on frequently poked areas of the screen. This makes the screen very easily cleaned with a few wipes of a cloth.

I've had it powered up for two weeks at a time without issue. Charging is not slow. My experience has been 2-3 hours to get to 95% from 15%. I did buy a cheapie 6' charging cable and it takes ~50% longer to charge. But I bought it mainly to use the tablet while charging so it doesn't really bother me. But a 6' cable is awesome! Do it!

Still happy. "No Ragrets" here.
