Re: W8.1 All the way...
@AC:
I agree on the progress bit but, like a cruise liner, you can't expect even an SMB to stop on a sixpence so there has to be enough similarity to allow the change to be accepted.
It seems to me this is what Win10 is planning - 'We're still as you remember us, but maybe you'd like to check out this feature' instead of 'YOU WILL CONFORM!!!'
