Don't forget that Wine or Crossover Office will both run on newer (intel) Macs and Xara seems to work quite well under wine.

I'm in the process of switching to Linux and I really don't want to have to leave Xara behind. I tried Xtreme Pro 4 on the latest Ubuntu and Wine the other day and it worked perfectly. I didn't do very much testing but everything I tried worked great and at pretty much native speed too - wine isn't a virtual machine.

The only glitch I noticed was that the transparent areas on all the tool bar button graphics were being filled in black. Looks a bit odd, but it all works and I'm sure it'll get fixed in a upcoming version of wine.
