Broke down and got a new (refurbished) desktop with Windows 7 Professional 64 bit with legal software. It is a HP 8000 bought through AAA Members program. $195 delivered.
Have it up and running. Being bombarded with ads and all the Windows Explorer crap. I use Google because that is what I know and all I am interested in learning.
I use my AAA membership a lot. While it takes forever, it seems, to get through to the dispatcher, and longer for the tow truck to arrive, it does save a hit on the wallet. I like the free maps and avail myself. A GPS is useful but I like to plot out my trips and Microsoft no longer supports Streets and Trips.
When I was deciding on the computer, I asked an expert (my sister's assistant). She assured me the computer has far more capacity than I will ever use (1.8T). Hope she is correct.
