I have been a computer professional since 1990, and a hobbyist dating back to 1981 (Vic-20, TRS-80, Apple ][). In 2002 I founded a networking company that I sold in 2008. Now my focus is on authoring an application to be sold in 2010. I've been a Mac guy at times and PC guy, too. We have six machines in our house (all Core 2 or better), and two are Macs... running Win7, OS 10.6, Vista x 3, and even XPP.
