Whats your definition as good matey?
Some people would say good for gaming. Others would say good for general stuff. Others would say good for being mobile (small). Others would say good for battery life.
I'm afraid you cant really get all four elements in one laptop.
If you want one thats seriously good for gaming, your best going for one like me, a desktop replacement.
If you want one thats good for general stuff, then any modern laptop will do to an extent.
If you want one thats good being mobile, then you would be looking at as light a laptop as possible, maybe a 12" screen.
If you want on thats good on battery life, then a lower end Pentium M (1.3Ghz etc) is a must to start, very little in the way of graphics power and a slower hard drive.
