I figured I'll probably need to upgrade when Macs are fully HD compatible (ie, have Bu-Ray/HDDVD burners, able to burn to 50 GB BluRay discs, can watch 1080i content, HDMI ports, etc). I know that Apple offically supports BluRay. I'd also imagine that the HD space in the HD era will have to expand greatly (i.e, 2-4 TB), given the huge amount of HD that a HD video would take up. HD discs can hold about 10 times the data a standard DVD. When do people anticipate that Macs will have these features? Also, will 1080p be the HD standard for a while, or is there something else right around the corner???
