I have found that HP laptops support ubuntu really well, though this is a personal experience here at my university. I have seen about 20 HP laptop (Compaq, HP Compaq and HP Pavilion) and about 10-12 desktops (Compaq and HP) migrating to ubuntu. Only some had a minor graphics issue, but oh well, they have an ATI! Mostly, I have found that with a small playing arount with backports and restricted packages, ubuntu works seamlessly! Yay! \o/
