My 2010 17" Core i5 MBP has been a power house for me. As a film maker having a mobile edit suite and data wrangler on location has been indispensable. Generally I find the speed and responsiveness on the unit to be great but I have found myself casting longing looks at the rMBP. The main thing about my 17" is the weight. Its truly a back breaker if I am also lugging around camera equipment aswell. On occasion I have wanted to started editing on the plane back from a shoot but the size of the 17" meant it just wasn't possible. The rMBP will be a massive reduction in bulk with the added bonus of Ivy Bridge and of course the higher res panel. However, I was using my 17" MBP just last week and thought just how remarkable it is to have a 1920x1200 resolution crammed into just a 17" screen. Is there much of benefit to be had with rMBP in this respect? I doubt it! As it stands I have decided I can live with the bulk of my 17" especially considering I probably only take it in the field 5-6 times a year. I think I will probably replace the internal HDD with an SSD and replace the DVD Drive with a 1TB HDD. Should give her a nice speed bump and then perhaps I could pick up a 11" MBA later in the year for rough edits and data wrangling on the road and portability. Any other 17" owners consider the rMBP and jump **** or did you decide to stick?
