It's worth remembering that Windows tends to alternate hit-and-miss (eg. Win95, Win2000, WinXP, Vista, Win7), which in some cases indicates experimentation with something new that didn't work out at first. Also, MS will really want to work on ARM. It's easy to port the OS, but legacy software (MS's key strength) is not. However, much recent software is written for their VM (.Net) and can be ported. It will be great for MS to make this leap - and every organization that is dependent on such software will be rooting for them. One would think the same would be true for Java...
