Even if Apple's iphone won't be seen in our hands until this summer, we now know that it will be powered by a version of the Mac OS X 10.5 Leopard operating system that will ship along side the iphone. Cos of the graphical nature of the Leopard makes it a nature choice for the iphone's large display, but will it be able to deliver when it comes to intense text messaging and sending long emails? Is their some form of predictive text input? Few initial users that had their hands on Iphone claimed that the software was smart enough to correct occasional typo's and also writing on iphone is much faster than standard mechanical thumbpads. Well whats your take to this issue?
