So, as much as I like the Mac, I've come to realize and accept that I'm simply unable to continue my Mac life. I'll continue to be an evangelist for their design, but the fact is, some things simply don't work as well as they do on Windows.
The final straw was my Palm and Entourage - I live and die by the synchronization of those two items. (It's all David Allen's fault) Lately, each time I sync my Palm, the Entourage Palm conduit crashes. So, I only have 1/2 of my items. And none of my tasks. Fatal, I'm telling you - it raises my anxiety level by at least 10%, because I no longer trust any of my systems.
So, I'm going back to Windows. It's a somewhat sad day - I'm back to a far cooler looking laptop (though I like the Thinkpad). But I'll be more productive, which will let me sleep better at night.
