What I really like with mobiles is that it is really Fun. A few years ago, operators and software vendors were developping applications and services to improve your productivity, to make you more efficient whatever the task you were pursuing.
Today Mobile is more playfull: you use application just because they are fun and just because you have some time to waste between 2 trains or 2 meetings.
This playfullness have even reached the business space. Professional applications need to be fun and nice looking too if Software vendors want to sell. Working will become less boring in the future and that’s a good thing !
