I bought TM1 in 2010 knowing full well that people have been waiting for TM2 for half a decade, because the presumption for late adopters like me (and possibly the parent) is that we bought TM1 to help fund the development of TM2--if revenue is really the problem for the delay of TM2.

I bought Sublime Text 2 while it was still a semi-working beta because I saw the potential and wanted to support the developer.
