It is amazing to see one person (or more accurately a small group of people, led by a single person) turn up the fortunes of a company. This is what I think Jonathan Swartz has accomplished. And quite spectacularly so!
First there was OpenSolaris, then OpenSparc the first open source processor (!!!!!!!!), Cool threads/Niagara, the ultra cool new AMD powered servers, Project BlackBox (incredible idea), Sun Grid, hiring the JRuby programmers...
And now, Java released under the GPL license. Nothing short of stunning!
Sun is a company to watch!
