My 2009 MBP shipped with Leopard and I upgraded it to Snow Leopard within a few months.  It was on there for a couple years.<p>My first computer was a Mac LC in 1991, and I was a die-hard Macintosh fan all throughout adolescence.  I learned to program with Think Pascal on a Centris 660AV.  My whole family continued to use Macs after I gave them up in 1998, so I certainly used them during that decade, I just didn&#x27;t like using them.
