did you notice any difference of an early 2013 mbpR 15'' from the early 2012 model?
Thank you
Screen looks more uniform and colors are a bit better, the keyboard feels a bit different. Performance wise very similar. I went LG---->Samsung

That's what I have now, 2011 13" with Samsung ssd.
That's EXACTLY what I had, a 13" Base with a Samsung 540 SSD I added afterwards. The performance increase is noticeable, and the screen....well you know because you bought one
