Many internet entrepreneurs I know (myself included) are pretty content sitting at the computer most of the time doing research and figuring how to generate traffic, improve web site design and conversion rate, and study web analytics to determine what to do next. We use the web for hours a day to do research on what everyone else is doing. Then, relying primarily on email and instant messaging, we can efficiently communicate hundreds of times per day with employees, customers, partners, etc.
Nokia will ship by the end of this year a number of new phones that offer rich multimedia capabilities. One of their phones has a 4 GB hard drive that will store 3,000 songs.
This is significant partly because in 2004 Nokia owned more than 30% of the global market for mobile phones, almost twice as high as the number two player Motorola.
