Why pick on me?
I work for a living. In the real world, I have to use PC based applications dictated by my employer, et al. Those applications are not available on my Macs. I'm okay with that. I can be a cheerleader for my Macs, but I can't dictate what a 20 billion dollar company decides is best for itself. I'm just not that connected.
I'm not picking, I am responding to your odd statement. I know there are some dedicated programs for Windoze, but most bizness apps are ported to Macs, as well.
What caught my eye, though, was your allegiance to the Thinkpad, and then your intention to buy a new PowerBook...
What programs do you use, that are so proprietary?
