I obviously tapped something in y'all with my post last week about Microsoft.
Looking at the comments, one point that leapt out is that Bill Gates is rich, and a lot of us would like to be rich, too. We look at Gates, we look at Linus Torvalds over at OSDL, and we wonder, is open source that financially worthwhile?
First, the comparison is unfair. Torvalds never was an entrepreneur, and so far as I know never wanted to be one. Gates is, and wanted to be one from a very young age. By all reports Torvalds is happy in his life and work.
Second, we are ignoring the elephant in the room, the one named IBM. IBM has re-invented itself through open source. Its stock price has not done as well as Microsoft's over the last five years, but it's in the ballpark. Before, it wasn't.
What used to be the "mainframe" business is now a two-horse race, and that is the battle I believe Microsoft will really begin when it releases Vista, this fall.
The ultimate answer as to which development model works best, in other words, is yet to be determined. But it is getting closer.
