DVD or the lack of it - just ripped /encoded a DVD using my PCs DVD drive.
So easy, I just shared the PCs DVD drive, put in the disk. Went to my Mac and found the DVD drive (listed with the other shared drives) Handbrake then encoded a 90 min movie in about 15 minutes to a 600Mb mp4.
And all the time the PC is sitting in another room sharing the same LAN.
Now tell me why you need a DVD drive in the new iMac?
What if the iMac is the only computer in your household or someone does not want to deal with Windows PC and component sharing etc
