I recently purchased this tablet for use in school. It was on sale at a big box retailer for $319. In addition to the already included MS office 365 subscription, this retailer also included an additional 1 yr subscription. I had also considered the Asus T-100. Things that stood out on this tablet were the extra long battery life, as well as the build in grip stand with the JBL speakers. Propping it up in class to view power points along with lectures is a pleasant experience. And many other students have wondered just which tablet it was b/c of its unusual stand. The grip is also nice when carrying it around, as I'm not afraid of it slipping (only care tablet, not both at same time, I use case for that) The keyboard is easy enough to type on for the minimal amount i've used it for that. A few points on the keyboard design I would mention, it does have a nice metal trim which classes it up a bit. The on/off switch I don't care for much, it requires a higher amount of effort to switch positions and isn't the easiest thing to do when nails are trimmed. Another design point i'll mention is that the keyboard and tablet both charge by micro usb that are located on opposite sides of each other, which can make charging both cluttered. The tablet only has one included charger, with a very short cable (like 2 1/2 ft cable). I can understand the reviewers comment about picking both up at same time in "laptop" mode. This would not work at all, and you'd end up dropping whichever one you didnt have your hand on, however... I feel that this isn't really an intended scenario, if i wanted to carry around an open and attached device.. i'd grab my laptop...
As for performance, I've only used it for MS Office type stuff, internet, Hearthstone, and the (free and amazing) racing game Asphalt 8 Airborne. All of these perform very well on the Atom processor. While I did not plan to do much, if any, gaming on this device, it is fun to explore its limits. For connecting additional devices, my Samsung OTG micro usb to usb cable works just fine. Logitech gamepad controller worked perfectly.
All in all, i've been very happy with this device at this price ($319).
