We've been hearing whispers about Nokia's touchscreen "Tube" phone for what seems like ages, and now it appears that the wait is almost over... with potentially less than inspiring results. In a statement released today from the company's head of devices, Kai Oistamo, the phone-maker says it will be launching a series of touchscreen devices in the second half the year, with the first model -- likely the Tube -- aimed at the "volume market." Oistamo claims that the mid-range market (not the high-end sector that devices like the iPhone 3G occupy) account for 50 percent of the total value of the touchscreen phone game. Essentially, it looks like Nokia's strategy will be business as usual, likely flooding the field with unspectacular mid-range phones, rather than taking on pricier competition like recent Apple and Samsung devices head-to-head, at least initially. Of course, who can argue with the company that shipped 122 million units in Q2 2008?
