Why are so many people expecting Google to enter new markets and revolutionize them? Their core business is extremely valuable and they will certainly face some competition there. If you look at some of the other tools they have released they are quite unremarkable.
However, I think Google taking GNU/Linux, sticking their name on it, and making a tight distribution would do a lot for GNU/Linux. However, this is a lot of maintenance work and valuable hours probably better spent elsewhere.
This is not a negative post about Google, they do a fantastic job. I am just wondering why people are expecting them to change the formula. Being a central "data core" is the future. Imagine the business when absolutely everyone and everything is wired. No more separate phone lines, everything will be done over the Net and guess who will be there to expedite everyone?
