Oh pffffffffttttttttt... How many versions of Windoze are there now? One of the biggest problems with any PC software is getting it to work with all of the various NT, ME, 2000, Office, 98, 95, ad nauseum, versions of the OS. Mac has two: 9 and X, and it seems unlikely P5 will support 9. That leaves just one OS to configure to, which I bet is far easier than all of Bill's many shills.
