Drop all antiquated ports, please
....but keep firewire.
Seriously, FW is in many ways superior to USB.
Most higher end amateur and and almost all pro audio gear (audio interfaces) are FW for a simple reason. USB doesn't ensure timing of packets transferred making it useless for audio work of any real quality. For me it doesn't really matter that much right now, but the next device on my shopping list is a FW audio interface. FW uses a different way of buffering which keeps the stream more even ensuring more accuracy.
FW also has a higher sustained data rate, again largely due to buffering methods. This makes a HUGE difference to everyone studying or playing around with audio or video.
Plus target disk mode is pretty neat.
Please guys, just ONE FW port.
I don't particularly like the reflective screen either, but doesn't bug me too bad. I don't always agree with their business or design decisions, but their design is still in general light years ahead of their competitors. Usability wise their hardware is the best I've used and OS X knocks anything else out of the water (any full OS for personal computers, that is) even with all its flaws.
Or as I sometimes put it, OS X is the least crappy OS on the market.
