I just bought a U330 a few weeks back, and the biggest dissappointment is the battery life. The boot jingle, hibernation problem, and the power adaptor sounds are annoying, but they are problems I can live with. However, getting a laptop that was supposed to get 5 and 1/2 hours of battery life but gets somewhere closer to 3 to 3 and a half hours (with settings maximized for battery life and very light usage) is something I can't live with. If this can't be fixed with better power management drivers, I would consider this false advertising, which is a serious deal in regard to possible lawsuits.
