Hello, I switched to Apple back in 2010 and I got a macbook pro. I edit photos in Lightroom and Photoshop and it has been a great tool for this. I felt it was plenty fast with the 12 Mpix files from my D700 and D300 cameras. However, when working with the huge files coming out of the Nikon D800 the performance is pretty poor. I don't know much about the Mac Pro but I was thinking about getting one just because it is upgradeable... Do you guys think the current Mac Pro is something I could use for the next 3 or 4 years? The new Macbook pro's are nice but not that much less money for something that might not last as long? I apologize if this is a dumb question I don't know very much about computer hardware. Appreciate any replies. Thanks.
