just get Lenovo. ive been using one for a while now and its of pretty nice quality.
Please note that i also have an HP DV series Core2Duo & an Acer Dual Core.
Best part about lenovo is the heat vents which are on the side and pretty big. My HP heats up quickly when on lap but lenovo doesnt. Its a nice practical machine no flashiness of pink or silver. Just plain black!
