Maybe you are writing about some non US currency?
Almost all laptops can connect to an external screen so later you can get one of those.
So my budget is around 350-370, I've noticed a lot of iMacs (2010 ones, to be exact) are very much within my budget and seem to be powerful enough for my usage. Problem is, I need a laptop for presentations and can't exactly carry around a 21" screen anywhere I go.
Anyone can give me a tip on what to do?
Buy a dirt cheap laptop with the iMac or just a powerful laptop?
