I think by "interesting" you meant to write "terrible".

Well, yes, but I was hoping someone would put it more eloquently, so thanks :)

I can't see what the target market is. The I/O is going to be terrible for hosting files. And 32-bit ARM is at a disadvantage for anything more computationally intensive (as you pointed out).

Maybe there's a group of users out there who have been thinking for years: "If only I could have my old smartphone colocated in a data center"...?
