Age old question, what do you want to use it for. And how portable does it need to be?
PCs/Laptops are a bit expensive currently, due to the way its globally priced in $ (and our exchange rate) and also a current Intel processor shortage (and you'd have to be Radio Rental to be looking at an AMD consumer oriented processor).
I don't play games.
I just need it for business, videos, and a quick access to porn.
I assume you mean watching videos, rather than editing?
If so, so you want something that will do stuff like MS Office, browsing and email? Spec wise, for that on a portable PC, I'd suggest i5, 4GB Ram, and an SSD that's big enough. Mobile components are not as powerful as their desktop companions. Though given you laptops rarely last the warranty period, maybe a cheaper i3 would suffice, as you'll replace in in 2yrs anyway
Portability was asked because there are larger latops (with a numeric pad on right of keyboard) with bigger screens, but these are heavier and less portable than the smaller ones.
If buying big American brands, stick away from the shite they shift through PC World etc, and go for the bottom end business ones - better end business ones will be well out of the budget sadly (though more robust)
