"TransferJet Technology"—does marketing speak get any more pseudo-tech-epic than that?
Sony's latest 8GB Memory Stick, now debuting in Japan, works just like any old overpriced Memory Stick. But, from 3cm away from a supported device, RF-based TransferJet can transfer the stored data at speeds of 560 Mbps (or, as Wikipedia reports, 375 Mbps in real world use).
Technically, TransferJet has been around since 2008, but it's just finally making its way to Sony products.
As for that Memory Stick's price, we have no clue. Sorry. [Sony via Akihabara News]
