I love my MacBook Pro, but the fact that
Apple is dropping the JDK would give me pause if I had to bet the farm on the platform right at this moment. OpenJDK is apparently
filling in the gap, but I've seen some
problems reported on Ubuntu Linux with OpenJDK.
Another thing to keep in mind is that you can also run Windows (or Linux!) on a Mac via Boot Camp or
VirtualBox, so if you do run into something that just plain won't work on OS X, you still have some options.
