But that's not messing up the PC ecosystem. PCs running Windows will be just like PCs running Windows always have been. Tablets and other ARM devices will be just like tablets and other ARM devices traditionally have been; the OS that comes preinstalled is the OS you have. You've really never been able to install, for example, Linux overtop of Windows on an ARM device before. The status quo isn't changing.
The only exception to the ARM rule in recent years has been Android, in a niche market, and only on some devices. That's not changing either.

Only because there's never been a port of Windows to ARM before.
If you want to claim locked-bootloader Windows RT devices represent a new class of hardware like, say, the Kindle, then I guess we'll have to see how they end up relating to the rest of the market.
