I seem to recall Intel was working on a few mobile chips over the past ~15 years. Or was it all part of the same drawn-out failure?

I also seem to remember shopping around for a new phone a few years back and coming across android phones running on what seemed like a Frankenstein Atom processor. At the time I thought it was a promising concept, though benchmarks weren't flagship quality. But I'd hoped to eventually see dual-boot phones I could slot into a shell of a laptop to have access to a an ultraportable low-end windows box when needed. I'm kind of disappointed that never came about. (I know there's some promising "shells" for android phones, but I'd really like an OS I can fully control for my desktop experience, and Linux phones don't quite seem mature enough)

Anyway, any insight on the above from your unique perspective would be welcome.
