It is about time that someone starts to address the problem of the Achilles heel of the iPhone, and probably many Android phones as well. Their lacking of a physical keyboard really is fatally flawed when comes to texting. You will have to look at the tiny keys to type, instead of looking on the screen of what you are writing. Even with the utmost of care you can still make many mistakes by hitting the wrong key on an iPhone. Another app tries to help iPhone users lookup contacts, called PhoneBook Plus, uses a bigger numerical keypad, but it is only limited to searching names, numbers and groups, not for texting. But still, it is easy to see a big difference PhoneBook already made. Siri may be a partial solution, but would be very interesting to see whether there can be a new revolution way of typing on a touch screen.
