more than a few of us use a Tablet PC. i like to be able to write down all of my client's info onto Word or Journal with my stylus. iPad doesn't have any good software for this yet. in that field nothing beats a Tablet PC (i'm not talking these "new" type of Tablet's that are out from Verizon etc...)
i recommend Fujitsu, here is my current model, it is several years old. i bought it off eBay last month:
when iPad has the features i need with great hand-writing software, i will def use it.
