I also have a single PC which I use just for Quick Books, as their is no Mac version as of yet. The PC has been fixed three times in the past year. It does burn CDs well, so fortunately, I have not lost anything.
Adding new software for the Mac is usually as easy as dragging a folder into the applications file. The PC makes me go through requests for notification of updates (usually telling me the software is out of date the moment I buy it.
Consider yourself lucky you didn't become a part of that 23%.
And the ease of installing software, I agree. It's almost as easy as installing software via Synaptic.(though right now I'm using Smart)
You can junk that PC... Quickbooks for Mac 2006
Actually, Quickbooks for Mac has been around for quite a while. There are several other options ... I use MYOB Account Edge for Mac.
