upgrading from Vista (and anything/everything before probably) felt like Windows 7 was a life boat
And it was/is
Windows 8 feels like a move away from safety
That was only really going to work if 8 looked and felt like 7 but got reviews it was 'faster, safer, stronger, compatible'
Microsoft doesn't seem to have used that messaging, they went with 'Look at my new interface' which is almost exactly what people didn't want.
just my tuppence from out here in the field
