Best ultra portable laptop?

Ill use this for college, wireless internet, blu-tooth, Hulu, music, videos, mild gaming, and connectability such as an SD card slot.

Price? preferably under 1000 but it's cool if it's a littler over
size? Needs good dimensions, probably like 13in. Its got to be portable, I'll be moving around ALOT
It needs to last me awhile, I just want it to be a joy to be with.

Capable to upgrade hard drive, RAM, and wireless 802.11n, and battery life if needed.



I was looking at the HP-DV3T


HP® Official Store — Buy an HP Pavilion dv3 and dv3t series notebook PC from HP

I'll order it with the upgraded GeForce G 105M and with a better processor. I can upgrade the RAM, HDD, Wireless Card myself (much cheaper!) and the education discount helps.

What do you guys think? Thanks, I appreciate it!
