I just picked up the Gateway M275xl. This thing is pretty tight. I payed 2300 for mine but got pretty much everything that i could get with it. I think that the base price is around 1800 but it comes nicely equipped. Just about 1" and about 5lbs. but the 14" display is NICE! Lots of real estate as opposed to a standard tablet; plus it is one of the only tablets out there that comes with an optical drive. A MAJOR selling point for me.... I had to get the DVDRW in mine. decent battery life ~4hrs. under average load (always doing something). You also have the option of the convertible to switch into a laptop, for when writing just isnt fast enough, or when typing is just more convenient. Check it out!
i have the toshiba m200. its the only convertible tablet thats also extremely portable at only 4 lbs. no optical drive, but it has a geforce 5200go.
im also a college student and use it as my desktop replacement in conjunction with the port replicator. ive played world of warcraft, warcraft3, cs, and ut2k4 on it as well.
