The AL iMacs are solid machines an'oll but I was wondering when they would carry the blue-ray or HD-dvd read/write capabilities. These disc formats are becoming pretty common pretty fast, both as data storage option and as preferred digital movie formats. I remember vaguely hearing about something to this tune a few weeks back, but nothing materialized as a macrumor. Would this possibly be a feature they could bring out at Macworld 08? Any thoughts?
