The Dells made in the past 2 years have shown significantly more problems at work than the older Dells. I despise Dell notebooks. I bought a fairly inexpensive notebook ($1100.00) a couple of years ago and replaced the AC adpater twice, but the most annoying problem was that the plastic case expanded so my RJ-45 cable would not stay plugged in.
Since I'm a webmaster and programmer for my company, I was allowed to buy any computer for my workstation and I bought a screamer from Velocity Micro:

and the cases are the coolest!
This Velocity box rocks (and so does my Sony notebook).
Don't get that Dell, dude...
