Either option requires a full copy of Windows XP to work > (i.e. you have to buy a copy). Minor quibble: Boot Camp requires a CD for Windows XP SP 2 -- nothing else will work (at least as of a couple months ago). Parallels will work with any version of Windows, DOS, or, in theory, Linux. In my limited testing, Parallels ran everything at full speed without a hiccup, though I did not run any games. Streaming video ran at full speed. Crossover does not require a copy of Windows at all. It emulates Windows APIs. This allows it to run without Windows, but must be tweaked regularly as the APIs change or compatibility problems are found. That's why applications must be certified based on the level of compatibility they have achieved with it. peter
