If Apple had to compete with someone else innovating on the PC, it would force them to break even further away from the herd. Macs are great, but they still resemble PARC's Alto from 36 years ago far too closely. The times have changed quite a bit. The iPhone is a much bigger leap as a personal computer (smaller leap as a phone, really).

The potential for innovation is there. It would be nice to see that happen on the PC. I hope that "someone else" shows up at some point. Better yet, I hope I can be a part of it. ;-)
