Every so often, Nokia will pop out a brick-like beast of a clamshell smartphone with a full QWERTY keyboard -- a black sheep in Espoo's lineup in every sense of the word. These so-called Communicators even had their own custom Symbian-based operating system, Series 80, until the E90 came around and brought 'em in line with the rest of the S60 crowd. Of course, S60 just took a big leap to the world of touch today, and that means the E90's starting to fall a bit behind -- so what's next? Nokia dropped a little teaser during its webcast today in the form of a stylized touch-based concept bearing strong family ties to the E90 and its ancestors, suggesting S60 5th Edition won't spell doom for the form factor. If it materializes, history suggests it won't be a mainstream device -- but if the real thing can look as good as this render, who knows?

A heaping handful of fresh alleged screen shots of S60 Touch's user interface are floating around, apparently yoinked off the platform's PC-based theme editor -- not as cool as if they'd been lifted from a Tube, granted, but still good enough to give us some clutch insight into where Nokia's taking this thing. As revolutionary as the move to touch control might be for S60 as a platform, the UI looks shockingly evolutionary so far; in fact, to the untrained eye, there are portions that are virtually indistinguishable from S60 revs of yore. That's good news (we suppose) for S60 diehards who aren't interested in learning a new paradigm -- and we're all for the VGA support here -- but it's bad news for anyone who was planning on having their noodles positively baked by Espoo's engineering manpower and massive R&D budget. Let's all just hold off on the negativity until Nokia gives us something official to ogle; for the time being, though, our boring UI-dar is definitely on high alert.
