Sony was showing off the PlayStation 3' s top level interface AT e3............The UI obviously borrows its appearance from kid sibling, the PSP, with some new console centric tweaks: there' s a " Users" menu, a web browser with some impressive (albeit very Mac OS X-looking) features, and " Friends" support for voice and video chatting, oh yeah, and gaming.It' s a sleek-looking piece of work (as is customary for Sony) but let' s hope the thing scales well from the start. With the copious amounts of functionality being bundled into Sony and Microsoft' s next-gen offerings, scalability should be central to the design. Of course, this is something Microsoft is (hopefully) rectifying right now in the 360' s Dashboard (right guys?).
