Hi all, I will be buying a 15" MBP this week and need a little help deciding. Could you help me understand a couple of things? 1st off, I don't mind buying refurbed. I primarily surf the web, but will now start doing some photo editing as a hobby trying to improve the photos taken with my new camera. I do not do any gaming. My questions: On the refurb site there is a basic 2.0ghz from early 2011, 4gb/500gb @5400rpm with HD6490 w/256mb of VRAM. I see in the fine print on the site that it says "memory available to Mac OS X may vary depending on graphics needs. Minimum graphics memory usage is 384mb." Does that mean the 256mb of VRAM will not handle the OS X? Do all early 2011 MBP's have backlit keyboard? Which is better? 750 gb @5400 rpm or 500 gb @7200 rpm? Is the 2.2ghz on the early 2011 15"MBP the same as the 2.2ghz processor on the current base model 15"MBP? Is the Current 2.4ghz processor with 6mb cache better than the early 2011 2.3ghz with 8mb cache? Sorry for the million questions....but this is a lot of money for me to spend, so I want to know I am making the best decision possible. Thank you for any and all comments.
