i personally would go with the dv6000t. inspirons are ugly as hell, imo, and the support isn't there. choose ur specs, see how the prices come out, and if the dell is like $200 cheaper, i might go for it. but that's how i am. first see how the pricing is on each laptop.
EDIT:
here's some pricing i got on the laptops:
HP DV6000t
CPU: Core2Duo T5500
OS: XP MCE (FREE)
Screen: BrightView Upgrade (FREE)
RAM: 1GB (2 Dimms)
HDD: 80GB 5400RPM SATA
Optical: DVD-RW
Networking: upgraded wireless card
Battery: 12-cell
Appearance: HP Imprint finish + microphone
------------
Total: $1092
Dell Inspiron 1505
CPU: Core2Duo T5500
OS: XP Home ($86 more for MCE)
Screen: highest one selectable
RAM: 1gb (2 Dimms)
HDD: 80GB 5400RPM SATA
Optical: DVD-RW
Networking: $25 upgrade (equivalent to the HP one)
Battery: 9-cell
---------------------
Total: $1208
so the HP comes out to over $100 cheaper, with a "better" operating system, 12-cell battery vs. the 9-cell for the dell, and looks a whole lot better. Imprint Finish (on the HP) does add a few fingerprints but it's also more durable.
if you feel like having more hard drive space, a faster CPU, etc., you have that freedom with the HP. i wouldn't purchase it just yet, though. when i bought by DV2000t, there was a free 1gb ram upgrade and 80gb hard drive upgrade...it'll save you like $75.
