I will move my Win applications to the Mac OS, but right now, most of my apps are Windows based.  I purchased a Mac (128k) in 1984, and a Mac SE 20 in 1989.  I also had a PowerMac 9600 in 1997.

Unfortunately, with the Motorola CPUs, the older Macs just didn't have the processing power per dollar that the Intel-based PCs did.  That has changes in recent years, so I'm going back to the Macs.  My nephew just set up his Toshiba core2 duo laptop as a "Hackintosh"-- he runs OS 10.5 in a Vista / Mac dual-boot setup.  He loves the Mac OS, and is also planning on buying a new Mac Pro soon.
