Is a tablet pc worth purchasing?

Im going to college soon and was wondering if I should invest in getting a tablet PC. I would probably get an asus eee pad transformer cause its awesome but i don't know if it is really worth it. Its main use in college would be note taking and surfing the web and simple stuff. Mostly note taking. So with that in mind would you recommend that or something else or nothing at all. Paper and notebook never worked for me cause i was disorganized so don't mention that. Thanks!!
