Not only that, but crossover loses out bigtime to Parallels, I looked at both, but I couldn't countenance buying something where _some_ apps worked and others didn't, if I was gonna invest in Win32 compatibility i really needed the full deal, which i get from Parallels (plus bootcamp, which is free, for 3d stuff). When I first looked, crossover lacked MS Office support, the main thing i needed, so it was a no brainer for me - parallels all the way.
That said, Picassa is pretty nice, but i get similar functionality out of Aperture plus Gallery running on my webserver, costs a lot more though
(rapidly becoming an aperture junkie - Aperture + RAW mode on my D50 plus 18-200 VR lens = pure joy)
