Hi. I need a small laptop. I have one now which is Compaq P3 1.2GHz 256MB 30GB HDD 12.1" ATI Radeon unknown GPU, no wireless. However my mom will be using it. So I need one for myself. I will only do e-mail, word processing, light Internet surfing, online chatting, watching movies, etc.

I require the following:

-Sub $500 CAD
-12.1" or smaller screen
-512MB of memory or more
-Capable of wireless connection
-Battery life of 2 hrs or more
-Have speakers
-Compatible with Windows XP SP2 (mainly driver)
-HDD size of minimum 10GB or more

-Having CD/DVD ROM a plus
-Having integrated camera a plus
-Having card reader a plus
-Having integrated microphone a plus

From my requirements, ASUS Eee seems good, but I need larger HDD space, like 15GB-20GB, without voiding the warranty or spending extra money on new S.S.D drives. And I don't want to carry an external USB hard drive, which eliminates the ultra portability and mobility of ASUS Eee, for its price.
Hence, does anyone have suggestions about any alternative laptops that meets my requirements? Or is ASUS Eee pretty much my only choice currently?
