Good point Barry that there are other solutions besides Quickbooks on a PC. With Apple's impressive success in the consumer marketplace with the iPod, iPhone, and iPad, we see see the Mac getting pulled into businesses more and more every day. The company I work for (xTuple, www.xtuple.com) offers powerful accounting and ERP software solutions that work on Mac, PC, or mixed environment. The products start with a free/open source version (PostBooks), and commercial Enterprise solutions as well.
