TLDR: If you want a cheap tablet with full Windows 8.1 that can run apps, stream Netflix, browse the internet, and check email this may be for you. It looks nice but does feel cheap when held compared to other high end tablets like the Surface(s). No full sized USB port is an inconvenience.
I had some hands on time with an Asus VivoTab Smart for a couple of days because a friend lent it to me. Overall, I really liked the size and weight of the tablet. The polycarbonate back does flex a little and won't feel as solid as a surface product, but it helps make this tablet that much more lighter. I also really enjoy the simple black, matte aesthetic of the tablet. The major missing component hear is a full USB port, so you'll need to buy a micro USB to USB converter for all your mouse and flash drive needs. The other downside is that this tablet doesn't turn on immediately when the battery is dead and you plug it in. It takes a few minutes of charging before it will turn on, which I've never experienced with another device. While it can run full Windows 8.1 smoothly, the hardware specs are pretty lackluster so dont expect anything past your typical web browsing, email, netflix tablet niche.
It doesn't seem like this comes with the TranSleeve or bluetooth keyboard, but many people looking at this tablet will probably be interested in them. First, the good news, I really like the keyboard. It's very thin and low profile; so while it has some flex, I think the chiclet keys were nice and spaced well for a tablet keyboard. You do have to manually turn it on and off as it has no sleep mode. It also has to be charged separately from the tablet since there is no connector between the two. It also doesn't work while being charged... So maybe the keyboard looks and feels nice but doesn't have award winning functionality. Next, the bad news. The TranSleeve, in my opinion, is terrible. Half of the sleeves have a manufacturing defect where it doesn't fold and maintain shape properly (read the Amazon reviews). And the magnet used to attach it tot he tablet isn't strong enough in my opinion, making everything feel insecure. It has this weird bar/pin thing that moves so you can squeeze the keyboard between the sleeve and the tablet, but it just doesn't feel reliable and strong enough as a cover or an origami stand. I do like the idea of it folding, and it can accommodate two different tablet positions, but the TranSleeve a poorly executed idea.
Overall, I liked my time with the VivoTab smart but didn't buy one for myself because of its price at the time. At this price point, its hard to pass up on the VivoTab Smart even if it from the dated first wave of Windows tablets.
