Owns his own business(but just starting out) and has a YouTube channel. His old 2006 MBP is dying and he needs a replacement. He makes iMovie videos all the time(5-15 minutes long) and goes out into the field to give lectures. I think the best combo for him would be an MBA and a 27" iMac to do his videos on. I honestly don't know whether to advise him on an i5 or an i7 and what configuration. The second thing is whether he should wait to buy the iMac now or will it be substantially updated in the next couple of months. I don't like the 21" because the RAM can't be updated and Apple's price for it pushes me to the 27". He is toying with the idea of just buying a non-retina MBP. He's been running everything on a MBP up until now, but I don't know the demands of iMovie making. I would think he would need to wait for a new machine to be out?? Has anybody got some educated opinions about what might suit his needs the best? Does he need to go with the i7 or will the i5 do the job with plenty of power to spare?
