What a bloody nightmare. Couple MS with Never finish One Kind of project In favor of Another.

Each version of Windows a complete rewrite, each incompatible with the previous, every year your OS becomes "old". Windows Update will deliver critical patches once a year, in service packs. UI department decides what the OS includes. If you installed games, you need to format and install the new version. Less options. Outlook no longer supports renaming meetings. Word decides to clock your CPU to max and pin it there. Winamp stutters. Windows Live reports your number to Microsoft. Microsoft site is cleared of whitepapers and reports and is replaced by an animated page in green containing specs.

Two months later, Windows is renamed to WiiGo enters beta again.
