Re: Microsoft, please don't add a start menu ....
I seriously doubt that an official Microsoft Start Menu will "kill" Classic Shell or Start8. Remember that the start menu is a part of explorer.exe. Worst case scenario is that you need to do a complete shellectomy and replace explorer.exe with something less asstastic.
Now, that would be a lot more work than knocking together a new start menu, but it wouldn't be the first time complete replacement shells were created for Windows. They'd cost a big of money, but after some initial proliferation, the world would settle on a standard set of two or three.
We aren't beholden to Microsoft for the UI. Quite frankly, I think Microsoft should go ahead and continue screwing the UI up royally. If Windows 9 doesn't have a positive reception form the market either then there will be real effort put into new shells. The viability of sticking with Windows 7 once Windows 9 comes out is pretty small. But we aren't going to collectively accept the design decisions Microsoft tries to force on us unless we actually agree with those decisions.
What's more, Microsoft can no more lock down the ability to replace the shell than it can throw out it's military contracts, contracts with banks, etc. There are lots of instances in which full shell replacements are in use in critical areas. It's just time they made their way into the public consciousness.
