Hello Guys, I have recently found this forum and would like to know what the experts think. I am contemplating selling my MBP 2.66 i7 500GB for the new 11" MBA i5. The pro is very fast however the portability of the air is what is drawing me to it. I recently purchased a refurbished 27" iMac so that will serve as the main machine for important stuff to run my small business. As far as the 500gb hard drive I have only about 50gb currently full so I feel the 128 gb would be sufficient considering the iMac I purchased has ITB. I do not travel that much except in the NY/NJ area and have been using 15" MBP's for at least the past 5 years so I am very use to the screen size. It would basically be an even exchange because of the depreciation hit I would take on my pro. Also I have the matte high res screen. Would this be a significant downgrade based on speed? Should I keep my Pro? Let me know your thoughts, thanks!
