i've got an early 2008 MBP and after the announcement i'm considering dropping an SSD in it, some additional RAM and getting a new battery to serve as my home-based back up machine (work provided me with a 2015 15' model but i'd like to keep my business and personal mostly separate). I was fully prepared to pony up for a new 13" but not for 2500$+ CDN with the specs I want...
An SSD will breath new life into your computer.
