Dear Mr. Douglas Perry, writer for Tom's Hardware...
7 years before the iPhone? Really? Because the iPhone came out in 2007 (even the article that you posted as source says so, if you even bothered to read it), so if Nokia had a prototype in 2002... then it's 5 years, not 7. You're not very good at math, are you, Mr. Perry?
And if you were to compare when Apple had a prototype (to make it a fair comparison), it'd be even less than 5. But anyway... Nokia may have had such a phone, but people demanded buttons at that time and they still did, well after the iPhone launched. It's why the BlackBerry was so successful. Moar buttenz!!1
