I see my 13" MacBook has already been replaced by a new model.
It's been moved to the "Pro" label, gained its Firewire connector back, and now has an SD slot (which I'd like for downloading photos).
Apple seems to be coming out with new models faster than ever. The model I have was only out for 7 months before being replaced! Most software doesn't get upgraded that quickly, let alone hardware.
I like the rapid improvement, but I hate the resulting feeling of being left behind! Too bad we can't get automatic updates like software :-)
