I have a dell Inspiron N4010(intel cor i3, 4GB ram), with Ubuntu 11.10. Was using Ubuntu on it since 10.10. Works like a charm, just sometimes the wireless(broadcom b43xx) doesn't work, which will work again by just turning off and on. It was shipped with windows at first. But it even works smoother under Ubuntu. Though I don't suggest you to buy Dell. I can see a fan problem with most Dell laptops that I've see and also cheap hardware.
