Joking aside, I think caution is good. I'm a long standing Windows ninja with a 25 year background in video game development, have been building my own computers for a couple of decades, find this stuff interesting, did all my homework and research ahead of time, and only upgraded after I was convinced it was going to be unproblematic
for me. So I think I'm about half-way between enthusiast and pragmatist on this stuff.
If you're not interested in messing around with configuring PCs, I'd say this: I think Win 10 is good, and I think we're all going to end up there sooner or later, but there's no reason to rush it. You can let idiots like me kick the tyres for you first. There are still 11 months of the free upgrade offer to go, so no rush at all.
