Apple primed mobile interest in 64-bit processors when it shipped the first smartphone (iPhone) and tablet (iPad) to sport such a powerful chip.
Now 64-bit processing is coming to Android devices. Samsung already said last year that it's working on 64-bit smartphones, and yesterday Intel's CEO said Android tablets running the chipmaker's 64-bit Bay Trail processor will arrive starting this Spring.
How soon soon Android apps will be available that take advantage of the extra processing power is an open question, but once the hardware's out there it should prove to be a tempting target for developers to take advantage of.
Windows 8.1 already supports the Intel Atom Bay Trail chip.
