Well, thought I'd try signing up for the new Windows10 "Technical Preview" to see what's ahead. I have run into a couple of snags (yeah, this IS preview software after all), but my general impression at this point is that, while it incorporates a lot of the new stuff that Win8 tried to push on us, the way it is put together is a LOT more intuitive. I'm running it on a non-touch screen, and I don't feel like I'm continually pulling teeth to get it to do something simple. Stuff generally shows up where I'd expect it to be. Surprisingly enough, most of the software (aside from VirtualBox drivers) that I've tried runs without a hitch.
Maybe this time, Microsoft has finally learned a few lessons from Win8, and will come out with something that is nearly as usable as Win7 was.
