My old Snow Leopard MBP was pretty much perfect in its day. It's long in tooth now but with a new battery and an SSD upgrade would still be well and truly usable as a general web-and-email machine.
Now replaced by a 2015 13" MBP, which feels almost identical (although that Retina screen is goooood... as is the HDMI port).
And I can still sell most of the 2011 MBP parts on eBay to get some of my investment back!
