I think it has to stay. I understand getting rid of the ODDs for laptops but I think desktops/real workstations still need optical drives. Losing a few mm/few fractions of a lb is significantly less important for a stationary device and it lets people who don't have an ODD on their laptop (MBA, possibly MBP?) have access to them without buying an external drive.
I hope they replace it with a Floppy Drive! Something just as useless.
Spend $30 and buy an external. Let everyone else enjoy a thinner iMac. If you Havnt converted over your CDs to MP3s by now you probably never will.
Is that a bad thing that there won't be a redesign? I don't really see what else Apple could do with the iMac to make it better, it's a gorgeous design.
No, I as well believe that the current design is more than ok. What could use a redesign is the MBP, to make it a bit lighter, but to be honest, I won't be disappointed if their design also stays the same.
I honestly have no idea why people are so hyped over unrealistic expectations (like the lol retina) and redesigns. If its not broken, don't fix it.
