Apple's Java 6 on Mac OS X available
Now the scoop is not that we had to wait 1.5 years before it to be available, but the fact that it only supports 64bit Intel processors. No support for 32bit, no support for PPC. Yeah, PPC is dead, but how many existing installations exist with PPC and 32 bit Intel? And how long you'll have to wait before there's a decent percentage of 64bit installations so you can put it as a requirement for your app? Not counting that if you bought a Mac earlier than 2 years ago, like me, you just need to buy some new gear to start developing with it.
Of course this is just whining. As a lot of people will hurry to say today, life is good, Apple is nice, and there's absolutely no need to worry about.
