nice looking mac, but my late 2006 black MacBook is still working nicely and as the new MacBook no longer has Firewire I won't be upgrading any time soon.
Think waiting 12 months or so is a good idea. There should be a big bump in specs by then. (hopefully Apple supported 8Gb RAM).
I see this complaint often, but I wonder if it's just a very vocal small minority, or a genuine problem.
