Defining characteristic at T100 is of course the eponymous ability to transform it into a netbook. In addition with the unit a keyboard unit, in which you can insert the tablet. Put together the T100 looks stable. You can use it to work properly, only gripe is that the screen felt three times as heavy as the keyboard. If you open up the screen more than 90 degrees (depending on how you sit can ever be necessary) is all somewhat unstable and tilts slightly to the rear. That's just happened to me to train every now and then. No huge drawback, but the keyboard with reasonable means, such as an extra battery to do a little more difficult, would certainly not hurt.
Conveniently located on the keyboard and a normal USB port, so you can plug in a mouse, and comfortable working with it.
Put together the T100 Transformer Book is indistinguishable from a netbook. Although I've been using mostly the screen as a tablet PC. Because the keyboard but almost takes away no space, you have always the possibility to work on the go and not having to take an extra addition a laptop. I am happy with the product. This also applies to the quality: Until now, there was nothing to complain, not even when the moving parts such as keys or the hinge for the screen.
A star I subtract (no unimportant criterion for a mobile device) and the unfavorable weight distribution for the whole fairly high weight.
Overall, I can the T100 but definitely recommend.
