I need to buy a tablet PC this week. I have been reading all the threads and have narrowed it to the Toshiba M400 or the Fujitsu T4215 but I am open to something else. I had had a Toshiba M200 which I loved and a Toshiba M4 which was too big but otherwise OK. I use my tablet in convertible mode as a regular laptop most of the time but on airplanes I use it as a tablet because there is no longer room to open it the regular way. Money is not my big concern. I want performance, features, and a great accidental damage and on site warranty (the toshiba one is pretty good and costs about $300). I have been reading that the Fujitsu may be slightly better in features but I have read reviews that their service sucks. Also that the keyboard may not be up to snuff. I have already read most of the threads including one that compared these two but my issues weren't mentioned. Does anyone have direct experience to advise me? Thank you.
