If you want a 17" Pentium M desktop replacement consider the HPZD7000 - the dedicated forum to read about that model from users and to find about all the discounts is at zd7000forums.com.

Pentium M (Centrino) notebooks give better battery life and portability but they top out at 15.4" --

Apple has the 17" Powerbook at 6.9 pounds but that is $2800 or over.

At the very least you can order the HPZD7000 online at hpshopping and get the $100 custom order rebate good through 12/1/04 -- there are also a 6% student APP discount, a 3% Fatcash rebate (sent later) if you sign up and go through their portal to hpshopping, etc... read the forum for details.......
