I have a Toshiba Tecra M4 that I've been using for about 6 wks now. It works great c AC. I draw pictures in windows journal, add them to the PE, and can review them prior to the next visit (bug with V3 that is being worked on now), all you do is download the free reader form microsoft onto your PC when it prompts you the first time. The microsoft download site has a ton of free software you can add to the tablet also. I take it with me everywhere!!!
