IDEA-IN presents the YUENTO branded calculator
that is shaped and has a similar key layout as a mobile. Clever, huh? The idea behind this molded bit-o-madness is that most human's fingers are rather adept at tapping away on mobile phone keys, so taking that insight a step further produced the "Mobile Calculator". Available in pink, white, yellow, and black. This, ahhh, interesting concept should set you back about $20 bucks if you can find one.
