Need techies here. Ok I have a both (2008 models) iMAC 3.06 GHz Intel Core 2 Duo 24" 4GB 800 MHz DDR2 SDRAM and MacBook Pro 15" 2.4 GHz Intel Core 2 Duo 4GB 667 MHz DDR2 SDRAM Question: Would a new 2011 MBP 13" 2.3 i5 be faster, or same as both or either of my iMac and MBP 15" I own now? Reason: I am consolidating I dont use them at same time. I need lighter smaller then 15" MBP but not lose performance. I do photo editing via PS and Lightroom, nothing hard core. I wanted to get a new MBP 13" to connect external monitor for editing, and something lighter and smaller on the road. I dont edit on the road, just small things conversions from RAW to DNG maybe. Thinking selling both 2008 machines for MBP 13" i5 and iPad2.
