Your friend most likely has some badass otter box type case that causes his phone to overheat.
Sure you cane use it as a baseball once its in this case, but put even a blackberry in this type of case and it will get hot.

What is your definition of teeny bopper app? Cause bejeweled would be part of mine!

Who needs a cable box, DVD / Blu-ray players or MP3 players, CD players ect… when:
I can connect my phone to any TV or home theatre equipped with HDMI and play any type of media through it. Music , movies, youtube, netflix and LIVE television.
I can do all of the previous wirelessly with any samsung TV’s
Still useing USB memory sticks for work / home?
I can use my phone as a USB stick. Just plug and copy any files / media from home to work.
Finally this one isnt for everyone, but still something a blackberry cant do
i can play ALL Nintendo, Super nintendo, sega, genesis, N64, gameboy, PSP games on my phone, should i feel nostalgic.
And before you tell me you dont need a phone to take pictures cause you have a “real” camera, you have a dvd player for movies, you have a ton of memroy sticks… i do too.
However when i want to take ALL of that with me on an impromtu trip, Everything i mentioned fits in my pocket and weights only 132 grams.

- Forgot to mention Andoid has actual GPS connection on not that cell tower triangulation crap.
That combined with google maps navigation (free) makes android phones a great GPS.
-
Android also has voice to text integrated in the phone. You dont like virtual keyboards? Why type at all??? Just talk! You can use this fucntion to send text messages, search on google, or make calls ect…
-
Voice mail and even visual voice mail is so outdated! ;D My phone transferes voice messages to text messages. No more pressing 1 to listen to new messages, 2 to skip message ect…
