tons of new and refurb W7 Pro systems available on Dell.com. W7 PCs will be sold for several more years. The enterprise did not convert to W8 and they won’t be converting to W10 either, and yet PC companies still want to sell some PCs. Go figure.
Best bets for Dell are Optiplexes and latitudes. Their consumer stuff isn’t very good.
If you want a desktop, there’s plenty of new W7 Pro x64 optiplexes (includes Dell factory onsite 3 yr warranty builtin) for sale at great prices at places like newegg.com and provantage.com. I buy these from both places all the time for both my business and consumer clients. They run around $615.00 delivered for 1TB HD, 8GB RAM, I5 Intel CPU, DVD-RW optical drive, etc.
Actually just bought a slightly used one configured exactly like that for $225 from Salvation Army.
I disagree, though, that the enterprise won't convert to W10. They have been involved from the start in the planning of the subscription model and see this as more advantageous than any new features, many of which are irrelevant for them.
