I love my T100 and all, but the thing is very cheaply made. You can tell just by picking it up. Heck, for some odd reason, whenever you launch the People app, the white balance on the display changes.
If I didn't need the desktop application support, I would gladly pay the extra to get a Surface 2 w/ Type Cover 2. Better build quality with better materials, better Gorilla Glass style screen with higher resolution, rear facing camera, full sized USB 3.0 port on the device, can stand on it's own without need for a dock or case, don't have to detach a dock to use device as a tablet (just fold keyboard back), more secure OS environment, etc etc etc ...
Edit: I'd also take a Bay Trail tablet if it was ~10", 1080p screen, Gorilla Glass (or similar), full sized USB 3.0 on device, HDMI or better video out on device, front and rear facing cameras, used premium materials for body like aluminum/magnesium alloy, had 10+ hours of battery life, and came with an attachable keyboard and Office for $600 or less.
Edit2: And on the discussion about the VivoTab RT. This is a last generation device that just hasn't seen a drastic price cut. I think you can find it now for about $350. Even then, things that the VivoTab RT has over the T100 is a more premium finish (metallic design), better dock with hidden hinge design and built in battery, rear facing 8MP auto-focus camera with 5-element lens, large F/2.2 aperture & back-illuminated CMOS sensor, NFC, Gorilla Glass, etc, etc, etc ..
