Replying to Will Cell Phones Replace Computers?

As we all know our world has changed a great amount in the past few years and it shows no signs of slowing.  One technology that has changed the most: cellular phone.  While computers have seen amazing changes and upgrades, phones have been totally redesigned.  Many phones are being redesigned as a small hand held computer featuring a phone.  With these upgrades to the devices, does it mean they will replace the computer.  They're already killing/killed the landline, calculator, and PDA/Calendar.  Is the computer the next thing to go or is there a limit to where the computer will have to stay?  Can we continue to type on the small QWERTY  keyboards or touchscreens, or will we need to be relieved with the ease and speed of a standard keyboard on any computer today?  Basically my question is: Will the cell phone replace computers?
