My advice is "don't", unless you absolutely must. Many people visiting this forum seem to think that a laptop computer is a replacement for a desktop computer. It is not. That's not to say they don't have a purpose in the world but you need to be realistic and don't get your hopes up.
I just found out that Lenovo G570 appeared in my country.
I can get it for $500:
Lenovo G570 Core i3 2330M 2.4GHz/3MB 4GB DDR3 750GB 15.6'' HD (1366x768) LED Glossy ATI-6370M-1GB
I like the design of the Lenovo more and it looks more ergonomic than the HP. But is it better than the HP G6 and is it worth the $50 more overall (considering all aspects like build quality, performance, etc.)?
