My early 2011 MBP had a logic board failure. I may fix it and give it to a family member. But am currently looking at getting a 15" rMBP (actually, already got one - but am still not set on THIS one yet). Really what I'm wondering about is the value difference between this year's models and last years. The 2.3ghz 500GB - 16GB model is $2600. Apple currently has an old model refurb 2.7ghz - 768GB - 16GB for $2339. Is there any reason I should avoid the refurb and spend more on a lower-spec'd new model?
