I'm curious to see what Parallels developers and fellow potential users might think of the concerns voiced by "PeterWor" over on the Apple forum: http://discussions.apple.com/thread.jspa?threadID=434122&tstart=0 In short, he claims that Parallels installs the equivalent of a rootkit, and therefore compromises the security of the system. I honestly don't know enough about the kernel and the Parallels mods to know how much merit his concerns have. These concerns are repeated over in MacSlash: http://macslash.org/comments.pl?sid=6081&cid=108843 Look, I'm really not trying to stir up trouble here---I fully intend to plop down my $40 for this software once I get my MBP this week (and 30" display too! yahoo!). Nevertheless I am interested to know what Parallels folks might have to say about this.
