It was interesting, but not very viable for anything that's of any measurable importance at all. I tested it out for a couple days to compile a little pice of code a mac user friend wanted to play with... it was dog slow on my system otherwise (but that was likely my system's fault, old E8400 @4GB ram at the time + Win7) -- Poison [BLX] Joshua M.

It's hard to get it to run at all, and when it runs, it's very slow an unstable. The only supported way to run OSX in a VM is with an OSX Host and VMware Fusion. I tried that too on my MacPro, it runs good, but it's not very smooth because you have no hardware acceleration (graphics) inside the VM. OSX is just not made to run in an virtualized environment. signature.asc Description: OpenPGP digital signature

Weirdly, their mobile clients (iPhone/iPad) are excellent (as far as the GUI is concerned, dunno about the technical merits of the underpinnings)...
