Mobile phone marketing

Why can't a mobile phone developer come up with a phone that encompass ALL the up to date, state-of-the-art technologies? Some phones come with large storage capacity, music player but no 3G tech.. Some with 3G tech, music player, but poor camera. Why? why not place everything together and name it the ultimate phone of the quarter.

I really hate making comparisons only to find that my stuff lacks this, lacks that.

Idealism has proven its non-existence again. Sigh.
