It mainly serves no purpose for me any longer - all the functionality I get in Gmail I can get in the Mac Mail app with Spotlight searching. The only "bonus" to Gmail is that it's web-based so I can access it anywhere... but I can also do that if I take my laptop with me. Also, I feel like I can take back ownership of my data if I stop feeding Google the text of all my emails so they can target ads at me.

Maybe I want to pop the G-bubble sooner. :0

I'm totally a Mac convertee/evangelist now. I'm really done with Windows systems for good, and I'll recommend Mac OS X to everyone from now on.
