Hello All, Well, my iMac 2007 model has finally given up handling the newest iMovie update (iOS 7) -- crashes and stutters. I still have my Macbook pro mid 2009 version w 8gb of RAM which handles the new iMovie pretty decently. I wonder how long though... But making these little 4 minute iMovies of my kids is important to me and am wondering next time I upgrade how powerful my computer needs to be. I think I'm done with desktops -- so my next upgrade with be either the MacBook Pro R or an 11" Macbook Air. I was looking forward to getting the Air since, aside from iMovie, what I need a computer for is very basic and I love the portability of the Air but now am wondering -- if I get an Air will it be able to handle iMovie? And most importantly I guess, how long with it be able to handle iMovie upgrades before it conks out like my old iMac? Will my 2009 pro w the 8gb RAM do okay for iMovie for awhile so I don't have to worry? I guess if someone has a better sense of what specs I need for iMovie now and the future -- RAM, processor, that kinda thing, would be greatly appreciated. If there a way I can beef up an 11 inch air to handle iMovie for the next few years or is it never going to be that kind of machine? Thanks for any advice.
