I'm currently using an iMac from 2009 running OSX Leopard 10.6.8.
I need this machine to develop iOS applications, and to do that I need xCode 4, and to use xCode 4 I need to have OSX Lion installed.
However I just read that OSX Mountain Lion is just around the corner, possibly coming out this end of the month. If I buy Lion for 30$, will I get Mountain Lion (valued at 20$ in app store) for free?
