One of the biggest complaints I have about tablets is their on-screen keyboards. It's just so unwieldily to try and type on while holding the tablet.
I thought it odd how many people were wowed by the Windows 8 demos; I didn't find much to get excited about except for this:
This way you can hold your tablet and type with your thumbs. I SO want this. I hope this is not some patent held by Microsoft. At the very least, I hope someone makes a patch in Preware for it.
