I just picked up an Asus GS1-X1 from Best Buy. It's more gamer oriented, but I absolutely love it.
$1050 for 4GB RAM, 1.83ghz C2D (could've gotten a better CPU online...), 320GB HD, gigabit ethernet, wireless A/B/G/N (most of the options online include Bluetooth), GeForce 9500 GS video card.
You can find better deals on Asus machines over at newegg.com, I just unfortunately needed one right away, without shipping.
Check out their F8 series or M series for more business/professional looking ones.
I'm severely impressed by the quality of the machine, and the complete lack of bloatware pre-installed (I removed the Office trial and the 90 day Symantec suite, and didn't have anything else I didn't want on it).
EDIT:
Some online suggestions (I'm very biased towards Asus at this point, since my Dell 600m was a PoS for the 3 years I had it, and my work-issued Compaq nx9420 loves to lock up whenever I attach a USB device, but the Asus I just got, and the one my friend bought a few months back, just seem awesome).:
Video in this one could be better, but if you're not gaming, it's great:

Better CPU, better video, different body style:

Better CPU still, more RAM:

There's also some really great 14" options - the screen has the same resolution as a 15", but is obviously a bit smaller. On the plus side, they are lighter, more portable, and get better battery life.
Cheap, decent CPU, great video:
