I am going through this dilemma right now MBP or MP. as the doubts of the future of the MAC PRO line are hanging over our heads and he power of the MBP makes it worthy of the label 'desktop replacement ' I believe this dilemma is tougher then ever. I have been using a MBP 2.33GHz Core 2Duo with the max 3 gig ram for nearly 5 years now (since 2007) and since the advent of Aperture. now with an HD upgrade, running Aperture 3 and CS5 I 'm realizing its time to get a new machine. I am well aware of the MP benefits with HD space and the scalability, 96 gig ram potential, 2 processors ... however, even after all my research I find the decision a tough one. I prefer the portability of the MBP, but do not want to compromise speed and raw power for portability, at the same time I question just how much of that raw MP power is being utilized by current software, Aperture 3 and CS5 in particular (as well as MS office and others). will there be a noticeable difference in speed between the MBP with 16 gig ram and a couple SSD 's with a thunderbolt external HD - vs - MP with 24 gig ram and two 6core processors, i would also like to get the 27" thunderbolt LED to join my 23" cinema DVI LCD, no problem on the MP, and i think id be able to do it on the MBP as well with the thunderbolt Promise Pegasus in line with the two displays. so there it is, a dilemma I know plagues many minds out there, lets see what the thoughts are on this issue at this present time 2011 to 2012, its a volatile and uncertain time not just in the economic world but in the world of tech. your thoughts will be helpful, thanks.
