There is a full review of this at Anandtech if anyone is interested. In summary, it's very the best when compared to the similarly priced Win8 competitor, but doesn't really stand out if you also include the Android and iOS devices, so it boils down to if you need those x86 apps. Also, the battery life is great at more than 8:30 hours of browsing and wifi.
Personally, this is great and I'm really considering it. However, I'd wait for the reviews for the Dell Venue 8 and 11, Microsoft Surface Pro 2, Toshiba Encore, Acer Iconia W4 and Sony Vaio Tap 11 to come out. (The Tap 11's review is actually already out.)
However good the T100 is, if I take a Bay Trail CPU, I'd rather go 8in for the great tablet experience without a keyboard dock. If I take a 10in tablet, I'd rather go for the Surface Pro, Tap 11 or Venue 11 for the Haswell CPU for more performance and I'd be willing to lower my expectation on battery life and form factor.
