I have been a tablet PC user from the beginning. Started with the Acer t1000 with pen, then x61 Lenovo, now x201 tablet. The Lenovos have been rock solid. I am an attorney and use this in tablet mode with OneNote for notetaking during client interviews. Then I use it in laptop mode to write briefs or lengthy emails. In tablet mode, however, handwriting recognition is excellent. After presentations, folks ask "Is that an Ipad?" I also have an Ipad but there is no comparison for doing actual work, notetaking, calendaring, writing briefs. The ability to use the pen to annotate Powerpoint presentations while they are projecting turns the presentation from a slide show into an interactive whiteboard. Big hard drive means not necessary to rely on the cloud, however 4g connectivity means productivity anywhere. Would like all this capability in a lighter device but so far, no dice. Hopefully Windows 8 motivates other manufacturers to design a lightweight, long battery life device that can do all this. The Lenovo x201 is not a computer for all people but for a user with my needs, it is perfect.
