I did hear about Windows 8 running on ARM tablets.
Yeah, but Windows on Arm can't run desktop software. They're Metro only, and...
There isn't much out there compelling for Metro (perhaps "yet", we will see, but that's what they said over a year ago about WP7, and I'd still argue they're nowhere near where they need to be).
I'm afraid that if Metro turns out to be another Vista sidebar gadget thing: with a bunch of shiny, but ultimately useless "featurette" apps, that eventually fizzle. And it could. They're making everyone re-write from the ground up. If they're going to bother to do that, why not re-write for the platform that is already selling millions and millions of devices per quarter, and where people
are spending money on software, rather than an unproven, untested platform? Then what do you have? You
can't run things like MC and Photoshop on Windows ARM devices (even if JRiver was
willing to recompile for ARM, Microsoft won't let them), so now you have... What exactly? A tablet that has some wizzy menus and widgets, but no real software other than Office, and... Less battery life to boot.
We'll see, but... Success is far from assured.
