In a recent press release, respected analysts Gartner predict that the "worldwide market for touchscreen mobile devices will surpass 362.7 million units in 2010, a 96.8 percent increase from 2009 sales of 184.3 million units."
The success of the iPhone has certainly contributed to this near-100% growth, both directly through its own sales, and indirectly due to other manufacturers emulating Apple's design on phones that retail for less.
Whether it's down to the iPhone or other devices, the predicted growth shows that users appreciate interactive interfaces of this kind.
