Re: Microsoft's conceited arrogance...
" This time Microsoft are so arrogant that they make not the slightest concession to people used to their "old" way of doing things."
While I agree with this to an extent, there reality is that a) for most of the PC era, the market for new users has exceeded the market of current users, and that is where the design specs are targetted; 2) PC users have shown themselves willing to dive into foreign mobile interfaces on iOS and Android, plus on home media centres.
The biggest markets for the old style interface are mostly in huge corporations where special install images are generally made to lay down a custom version of Windows and approved programs.
