Japanese researchers – a label with a strong post-WWII history for evoking efficiency in size and power consumption – claim to have developed solid-state storage technology that will support drives with no moving parts, no bigger than a postage stamp, deliverable by 21012, and offering a capacity of 1TB. They demonstrated a prototype.
The question is now how to make computers' UI elements small and low-power enough to match the improvements in processing and storage. Shall we jack the things directly into our heads?
More seriously, though, the prospects raised by such tech are pretty cool.
