I have one, have had many issues with it, and know of many people who had many issues with it. Luckily, I paid quite a cheap price on this laptop. If I hadn't, I'd feel very robbed of my money. All in all, I've heard many, many stories (bad) about this laptop and Dell in general. I think I'll stick to building my own computer.

Dell had some troubles with the Dell 1100, 1150, 5100, 5150, and 5160... all very similar. They were fixed for most users while under warranty. You might want to talk to Dell Tech Support on the phone.
We have several clients with this laptop who are now quite happy with it.

I have talked to Dell Tech Support on the phone. Of course all the problems occurred mere weeks after the warranty ran out.

If they knew about the issues, and you talked to them while still under warranty, they still have an obligation.

Hm, I've had this one for about a year and there are no problems at all... And what kind of troubles did you experience? (I want to be aware what to wait for) :)
