A while ago I asked if many had first hand experience using the final cut studio on the core i7 imac. At the time, actual firsthand experience seemed rather limited. I am basically looking for an update on this situation. Has anyone here used the studio a decent amount on the core i7 imac, working with HD video? I was curious as to how the performance is working out. Also, I was wondering what the best solutions are to external storage, as this appears to be the most glaring short coming to editing HD video on the imac. Also, as a quick aside, does the 27" i7 use desktop ram or laptop ram if I wanted to add ram after I purchased the imac. Thanks for any/all help and advice!
