I still wait for the day where smartphones become the only computer for most people.
dock it, (maybe cool it) and the available power is significant.
google is definitely taking steps there with their virtualization work and desktop mode, just slow.
Apple may be too, with their switch to ARM on desktop.
I wonder what the effective radius of these things was (and what it wad expected to be)
low amount of explosives + low density shrapnel may have made this basically a touch-distance weapon.
