I do care about Windows desktop changes. Not for me, but for my mother, over 80 years old, and although she still can handle changes, it becomes more difficult. She's using Windows 7 right now (coming from XP via 2000 and 98), with the classic (grey Windows 2000) design. I hope that stays with Windows 9. I'm very glad we could skip Windows 8.
I guess many older people will have these problems, and I can't understand that MS has no clue about the first generation of elderly people using computers.
