This was Nokia's first dual touch-and-type device, designed primarily to bridge the gap between the two kinds of devices that were emerging at the time of its launch in 2010. But it didn't come with multi-touch capabilities and the screen resolution was the same as the old Nokia Series 40 devices -- 240 x 320 pixels. However, the device came with Facebook and Twitter applications and boasted a 5-megapixel camera -- at the time it was rare among low- to mid-end smartphones -- and contained powerful for-the-time hardware to keep the device ticking over.
While many devices with a physical keyboard nowadays offer the touch-and-type capability, such as the BlackBerry Bold 9780, at the time many found it confusing, as you would have to literally touch-and-type. You couldn't use one or the other, and many found this too complex. Plus, Nokia's implementation of the dual-input methods left little to be desired.
