Thinking of buying an Acer then?
Why are you after laptops? I prefer desktop PC's for business as they are easy to fix
I would have thought that you could go with a fairly generic model unless you are running software something like Pro Engineer or work in digital media production. Won't you just need the full office suite and something like Sage?
This model looks pretty good to me for £399.95 inc VAT
