First I was a little disappointed when Apple released their specs for the new iPhone. I won't buy one for many reasons but since everybody is eager to build an iPhone killer it seems to be a good pointer for future development of smartphones. Then after some thoughts I was impressed because Apple decided to go with software and not to split their user base among many incompatible hardware.

I don't know if smartphones are already at the point where every new PC had to be MS-DOS compatible many years ago, i.e. hardware is just a part of investment and software becoming more and more valuable investment that is well worth to be protected.

It seems that Nokia still sees themselves mainly as hardware company. Otherwise they would at least tell something like we will do our best to ensure that future versions of software will run on as many smartphones as possible.
