Tablet PC's?

Hey I am planning to buy a new laptop for med school, and I was thinking about getting a tablet PC. Is anyone else planning to do this? I was looking at the Toshiba ones because they have an internal CD-RW/DVD-ROM drive, whereas the Lenovo (IBM) ones don't. My brother informed me that Toshiba is coming out with a new one in the next few weeks that is a 14.1" screen, compared to all of the current 12" screen ones. I know they are supposed to be putting up computer recommendations on the admissions website, but I was just wondering if anyone else has been researching these yet and has any input. Thanks, guys!
