I've definitely gotta get a vote for Gateway. I just bought a M320X thats about 1" thick and ~5lbs. Stats:
512mb PC333 (think its 333)
Intel Extreme 2 graphics (only main weakpoint)
Pentium M 1.6 GHz
Win XP Home
3in1 Media Reader
4 USB 2.0 Ports
High Capacity Battery (4-5 hours usage time)
UltraBright 15.4" Screen
10/100 Ethernet Port
Wireless Ethernet B/G
Dunno if I'm missing anything important...Anyway, Total Cost, Shipped: $980 after $200 instant, $200 mail-in rebates, and free shipping($50). I'm 99% sure Dell can't match this. They give you a skimpy hard drive and little ram unless you pay for upgrades.
Also, I've had a Gateway 733 Performance PC that's been running strong for like 5-6 years now.
Yes, but no sprinkles. For every sprinkle i find, i shall KILL you.
