Hi, I have an early 2011 15" Macbook Pro i7 2.0 ghz with 8gb ram and an ssd. I do not complain about performance, some hang ups but nothing more troublesome that a restart cannot resolve. New 15" Macbook Pros are thinner faster cooler all that but I would like to read what others think about this. I have no reason at all to sell my laptop I paid close to 2K for it and yes time has passed but If I upgrade to 16gb ram and a new battery as long as OSX continues to support my hardware I have no reason to get a new one. So, what are your takes? Should I sell or keep it and upgrade the ram?
