Safari, Internet Explorer, Firefox for Macintosh all work just fine on flyertalk. You should be able to connect through your cell phone to the internet without having to use Virtual PC. If you need Virtual PC for running any other windows programs, I strongly suggest you get at least 1/2 a gig of ram in your PowerBook, and use Windows 2000 for optimal speed and efficiency. The upcoming version of Virtual PC hopefully will increase the efficiency of XP running on OS X. Enjoy the new PowerBook, I have a 12 inch PowerBook that I use as my primary computer and it works wonderfully.
