Thank you for the info, the disto sounds interesting.
Based upon how seamless the VM relationship works now, even with bluetooth, I'd would say it's a safe bet that it should work. There may be the intitial selection of the shared resource one way or another process [Mac side vs. MS side], as is the case with using the CD drive, etc. You need to eject it from the Mac side before the MS side sees it.
Bluetooth seems to be seamless allowing both at the same time, like using a bluetooth keyboard or mouse. Just have to make sure you have the correct window selected. Haven't found anything that does work, except for network printing.
I have a Sharp MX3100 that needed a postscript module to allow printing from Macs. The MS side going through VM worked fine though. Macs need a postscript printer. Other than that, no glitches.
I am familar with the Xactscope, just haven't used it, so cannot comment. Again, I'd be surprised if it didn't work. No reason it wouldn't.
Your right about Mac handing the graphics better. They are not crash proof, but just crash much less often, and even if I do not do a fresh restart once a day, more like weeks sometimes, it's still a surpise when a lockup or crash happens.
It's rare!
The air vs. the pro?..I'd get the pro. No reason, just the indended use and the horsepower for the money, the pro just seems better.
