Uhm Dell is very good for it's support and service, I bought my dell true school, and bought 3 years garantee + 24h service.
SO I didn't need it but a classmate did, his lcd broke so he called an the other say they came along and replaced his LCD, for free, as part of the service.
Another classmate couldn't boot anymore, so he called dell to, next morning, someone came and looked at it, then replaced the motherboard because the onboard video card was broken. Again for free ^^ . if you call this bad? It's much more expensive to have it repaired by some other shop.
