We’ve seen the concept of a horizontal slide-out QWERTY keyboard on the LG Rumor and a number of HTC smartphones, but I think this is the first time that I’ve seen the form factor in a Nokia. Although not officially announced by the Finnish phonemaker, what you see here (on the left) is the Nokia E75 smartphone.
You should know from the E-series moniker that this is a business minded device. It has a similar form factor as the LG Rumor and HTC S710, offering a numeric keypad in its closed position and a full QWERTY keyboard in its open position. More likely than not, it’ll be powered by some variant of the Symbian operating system.
The phone on the right is the Nokia N72, which takes on a more familiar form factor for Nokia. It’s similar to the E71 with its candybar QWERTY-ness and such. No other details are available yet.
