I know I'll get down voted for this, but oh well.
I don't see why Apple can't consolidate the MBA & MBP lines into one single MacBook line. Have 11", 13" & 15". Drop the 17". MBA form factor. USB3. Retina display. No ODD, no Firewire, no ethernet. SSD stick drive.
As for iMac, drop ODD. Maybe drop ethernet & Firewire. Gain retina display.
Drop Mac Pro entirely. Port Xcode to the iPad.
I'm not saying I like this way of business, but I find it goes w/ Apple business philosophy. Very simple product lines geared more towards consumers. I have a 17" MBP at home that I enjoy, but from a business perspective, Apple should focus on what gets it the most profits.
Agreed on all points but I don't see Apple dropping ethernet ports from desktops.
