I did my leap of Faith in 2001 and I never regretted it one single second. Now I got my second powerbook and they are, well, awesome to say the least. And Spotlight in Tiger just rocks.
Not to mention that you have the best office software that exists in the market. M$ Office 2004. Though it remains to be seen how this works out with Entourage and Spotlight (currently I index my fastmail.fm account using Apple Mail, but read all with entourage).
