Hey folks, I'm about to sell my mid 2009 MBP (2.26GHz C2D/8Mb 13") and plan to buy a 2012 MBP (hopefully with retina display). Anyway, I also have a 2010 iMac i7 2.9GHz 27" with 12Gb ram and the Apple 256Gb SSD. That machine is very fast and still more machine than I probably need. My question is: are any of the current mobile i7-equipped MBPs going to feel as fast as my iMac? Has 18 months of i7 improvement brought the current mobile chips up to the level of the 2010-era desktop i7s? And is there anything else about the architecture of the imac that might make getting that level of performance out of a MBP unlikely? I'm really hoping someone with a similar iMac can let me know. Second thing: logic would make me think that an i7 MBP would use a fair bit extra power over a C2D MBP - is this correct? I'm getting around 3-4 hours from a full charge on my MBP (2.5 year old battery, OCZ Vertex 2E 240Gb SSD) - what's typical of (say) a 15" i7? I'd be happy even to reach 80% of the performance of the iMac in my new MBP, but wouldn't want to do so if the battery life is dramatically reduced. Any tips/advice?
