USB3 is lacking in PC hardware as well, apart from the top end products. I couldn't care less about USB3 until Intel finalizes their silicon and brings faster and more mature products than the NEC chips in use today. The USB3 devices are in their infancy as well. I don't dispute the fact that USB2 is a bottleneck for external storage.
However, Apple has made several poor decisions on the hardware front:
- Blu-ray is still not an option for these machines (because Apple knows what's best for consumers, right?)
- Displayport is fine, but why, oh why the Mini version? It's not like this computer didn't have space for a regular one.
- Only 4 USB ports. Double that would be the standard in a PC.
- Firewire 800 - a dying breed even in Apple's eyes. Many (H)DV cameras are supplied with only USB these days.
