Argh..I just ordered it! Couldn't find a whole lot about this issue  
online, except that 1.6 isn't included, which doesn't surprise me at  
all. I'm wondering if this mainly impacts visualization or if it is  
GUI in general (I don't care so much about 1.6 improvements to Swing  
as I'm spending much of my time in Eclipse these days..) Or..eh..if  
it is Java performance altogether, that would really suck. I think  
I'll install it on my wife's MacBook first..
