old thread but I got very enthused about table PCs. I am replacing my older Lenovo laptop with the i7 X201 tablet. Just to be able to draw and annotate and create presentations that have drawings in them and have a real heavy duty Windows laptop which I always need to have (for Camtasia, GoToWebinar, and miscellaneous that runs best on Windows).
And yes, I have an iPad and love it. But the Tablet PC is fantastic for what I bought it for and as a replacement for the older Windows machine. It is really small, very lightweight, battery life seems around 4 hours, and the tablet is very, very handy.
