By full size keyboard, I mean one that that is not compressed down to tiny buttons.
CD-RW isn't really necessary, since I'll be using the USB and Wireless to access any off loaded information, but I've seen an option where you can slap in a secondary battery to extend the life of the laptop to at least 7 hours.
Pretty much from what I've read, 512 MB of RAM is required not to have a sluggish experiance with today's (current) software. Hard drive, I could really care less if it was only a 20GB (I've been using a 20GB on my PC now for years, that I still have yet to completly fill up. Not to mention that any data that I won't use that often will be backed up via USB or Wireless to my server.
Mainly, I'll be using it for college life (taking notes, word processing, reading email, surfing the Net, and some light coding for when I need the extra 5 minutes to cram before a programming class
), Organizing my role playing, and keeping up with
A.net when ever I'm at my local Starbucks or Panara Bread. I occationally might play something like Rise of Nations or Age of Empires II.
