I'm reading this and handwriting my reply on a Lenovo X41 Tablet so I can vouch for their ability to build a quality product that remains upgradeable. (I'm running Win7 & this was designed for Win 2K Pro or XP.)
I just think they missed a bet by not calling it a LenoPad...
Next questions are: Will it be Atom based, how big, and how much?
The real question is how long before someone leverages existing technology and improves the user experience by letting you spell out your input with a finger like you'd do with a pen, rather than pecking at an unyielding onscreen keyboard substitute?
