I'm certainly convinced enough to want to use these features, on a Mac or not. It's easy enough to switch between Windows and Mac with Boot Camp. And frankly Windows 7 with that security essentials pack I mentioned seems just fine. Not pretty but it works. I've just revised a 125k word book in the Word 2010 beta - no crashes, no problems at all. And actually it feels faster in Windows on my Mac mini than Mac Word - as does Chrome.

It comes with macros disabled (I never use them anyway). So I don't think a macro virus could get you (though I know nothing about them).

My feeling is the Mac versus Windows argument is a lot less clear cut than it used to be. This ThinkPad Edge is definitely my portable machine from now on I suspect.

I also have to say I don't like the way Apple is going as a company with behaviour like this http://www.theregister.co.uk/2010/05/05/ellen_degeneres_apologizes/
