Home basic vs Home premium (vista)

Hey guys, i need to buy a laptop which will get me through uni, but i don't know enough to decide which one.



But, i just wanted to know the differences between the home basic package which comes with some laptops, and the home premium which seems to be on more expensive laptops..

What makes them different?



I need it to do powerpoint presentations, and word processing, as well as games and the usual student stuff.

I have so far these two laptops in mind:

Thanks guys, any help will be gratefully received.
