I missed this in the announcement of Schwartz taking over:

Sun's vision is more relevant today than ever before and is embodied in the product and service breakthroughs it has recently brought to market - from the 'pay-per-view' utility computing Sun Grid and the eco-friendly 32-processor-on-a-chip Coolthreads system, to Sun's innovative software pricing model for the Java Enterprise System and the open sourcing of Java[tm], the Solaris[tm] Operating System and the UltraSPARC T1 chip. The industry has clearly recognized Sun's innovation and the Company has received scores of awards, including Best Server Solution from Waters and the eWeek Excellence Award for Solaris, and is setting numerous record-breaking benchmarks with its UltraSPARC and SunFire systems.

I added the emphasis. The revenue from Java (such as it is) for Sun is in licensing. If they toss it out as Open Source, that would presumably end. Exactly what benefit would Java development bring Sun then? Especially given the fact that it removes any real need for you to use Sun hardware?
