thanks folks, I think!!!, maybe I'll just leave you to carry on trashing without me for a while. I will report back if I have any actual problems and what, if any, workarounds I had to use.
Thankfully, despite the dire warnings, neither my PC nor my eyeballs have exploded due to using W8 and, so far, I've been able to access all my files and my experience doesn't feel much different. I don't have a problem with turning off bits I don't want as I go through a new setup and I even know how to turn them back on if I want to.
