I agree I don't think Vista was as bad as a lot of people were making out, and about developers complaining for reasons Splash mentioned - I originally tried it apprehensively, but quickly realised it improved a lot of things over XP. However, I think UAC was too in-your-face for a lot of people, so it ended up having the opposite effect of what it was intended for because of idiot 'experts' posting guides on every other website about how to disable it. Windows 7 fixed that problem, and most of the other annoyances with Vista
IMHO.
However I don't feel the same about 8 - I tried the various trial versions and simply didn't like it. I'm not 'stuck in the past' for not wanting to use a UI which simply doesn't suit my usage model as well as 7, and I'm tired of seeing condescending comments calling people Luddites or whatever for not wanting to inconvenience themselves with a pointless upgrade/downgrade.
As above, PR are the ones claiming it's all better/shiny/new, it's up to individual users to think for themselves and decide whether it will be useful to them or not.
For £25 though, it might be worth having in case 7-8-9 is cheaper than 7-9, and for the longer support period than 7.
