Pros:
-Nicer graphics than xbox with hi rez and anti-aliasing
-Minor "Special edition" features
-Overall, runs nicely.. so nice to not have to restart into Windows
Cons:
-Not very much new.. and nothing new specifically for the Mac version to justify the cost
-Some features missing from prefs (you have to edit the prefs file manually)
-Manually enabled Mouse Look can do some funky things
-Also FSAA can cause stability problems
-Game controller buttons need to be manually edited, and not all buttons work
-Some features missing entirely (like the rotation during pause)
-The hoops one must go through to use the Windows-based saved game editor on this cider version are many
-The "Master" mode (once you complete the game) is exceedingly difficult
