Sometimes, I wonder why Apple doesn't just merge the two lines? That would make the laptop line a whole lot simpler. As many people have stated, Apple is going more for the consumer rather than the pro market. Many of the things you'd lose on the pro like optical drive and firewire, you can make up with external devices and adaptors. Sure, I don't like that, but it's smart business sense.
One question though: when will Apple release new MBPs anyways? Just wonder if it'll be before or after Mountain Lion's release. I doubt it'll happen, but it would seem a little silly to ship them now and then have ML ship in June. But then again, that would also mean that Apple could just get more money from those people.
On a tangent issue, if Apple gets rid of the optical drive in MBPs, when will Apple get rid of the drive on iMacs? MBAs and the Mac Mini lost their drives years ago.
