Have you considered buying a refurb older model 2.2 ghz whitebook? It's faster than any whitebook available now. (current model is 2.0ghz)
I don't think that's true. The 2.2GHz is an older 65nm Merom (Late 2007 MacBook), whereas the new 2GHz is a 45nm Penryn + faster FSB + much better graphics. It's faster.
One thing it doesn't have though is Intel VT-x hardware virtualisation support, which maybe doesn't make much difference using Parallels or Fusion but does matter under Windows Hyper-V for example.
RedTomato said:My workplace has bought 3 of the 2ghz whitebooks (after Apple stopped selling the 2.2ghz, but before the recent graphics upgrade), and I've noticed they seem not quite as smooth or fast as mine. (with the same RAM as mine)
No comment on the new 2ghz whitebook with upgraded graphics. Just a reccomendation for the older 2.2ghz whitebook if you can get it cheap and don't mind the graphics card.
Edit: OK, I think you're confusing the MacBook models here. If they bought 2GHz models then they're the same vintage as your Late 2007 2.2GHz, so yes of course they'll be slower. You won't get an older 2.2GHz model as they stopped selling them in February 2008.
I think you might mean the later Early 2008 or Late 2008 2.1GHz models.
