Should phone be strictly for communication use?

When I got my new iphone, I do not expect to use it for anything else other than to access internet while on the road. I believes that the phone should be strictly be used for communication - voice call and text messages. But ever since I could access some good tools, apps offered from the Apple store which are free, I started to download other free apps which are games. Mostly are the puzzles type. Since the games are free, they are usually the lite version of the full game and I don't really care much. That is until I found out that a some websites post some exclusive free apps for a limited period that I started to download them since they are free. Some of the games are addictive and now my iphone occasionally became my portable game console. While I do not play all the games I download, only the very few addictive ones, I am so far able to refuse to play music and video from my iphone. I have my mp3 player and as for video, I hate the long process of converting videos for use. My thinking may change and technology improve in the future. Right now, my iphone will be strictly communication, and for my entertainment in those few minutes of my spare time.
