This might be a stupid question, but does processor speed affect the speed at which you browse at? For example, I have an iBook G4 800. If I stepped up to a 1.5 ghz Powerbook, would browsing the internet be substantially faster than with my iBook provided I am still on my breadband connection here at home? I notice that loading web pages sometimes takes forever and sometimes it is really fast. It usually doesn't matter if I am on wireless or ethernet. On my old 2.66 ghz Compaq laptop, I would be able to load web pages really quick.
