Phones vs. Computers

Everyday the computers get smaller and the phones get smarter. Will phones one day replace the need for computers? I understand that people that work on the computer will still need them. I'm talking about the average person. I hardly use my computer now that I have a BB. If I had an I-phone I could do anything my computer could do and fit in my pocket. (One day apple will change service carriers and you will also get to use the phone feature.) I still feel the need for a laptop with the wifes home business. Today I twittered, Facebooked, looked at my fantasy football team, asked google a question, and did this post from my phone.
