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?
