font support
I just dealt with the font issue last night in taking an old logo design actually done in CorelDraw and opening it in Illustrator on OSX... the font files were missing, so it loaded up alternatives which weren't what I wanted, so I went and found those font files, copied them into the Fonts folder (either in my personal Library/Fonts folder, or the system one, they both work) and it worked perfectly. I even purchased a library of fonts from Microgetics (advertised as PC only), extraced the .exe file on my windows machine and installed it, then went into the fonts folder on windows, copied them all across my mounted folder onto my OSX machine, then moved them into the Fonts folder in OSX and they were right there for immediate use. The only thing is that they have nasty DOS names instead of nice Mac full string english names in the folder, but in the applications, they come up perfect. Using FontViewer I can browse through them all just to be sure.
I was very impressed by the ability to copy TrueType fonts around completely without regard to which Operating System I was using.
As of last night I have no fears of dealing with fonts in OSX, and it didn't slow anything down by adding 150 fonts in either, which I've had older Windows machines do.
