Silicon Valley is the best place to start a tech company in so many ways.

International markets are much bigger than the U.S. In Sweden we have 9 million inhabitants, and if you're successful in Sweden, you're not successful - it's such a small market.

Today, over one million people now make their living on eBay, which is astounding.

Another differentiator is that Skype is free and simple to set up, and it costs us virtually nothing for a new user to join the Skype network, which is why we can offer the service for free.

Skype is easy enough to use so that people don't need to be tech savvy - a lot of users just want to communicate with their friends and family, and they find this is the easiest, cheapest way.

People need to access Skype wirelessly, no matter where they are, and what happens is that we'll be taking advantage of the rollout of Internet everywhere - WiFi and WiMax in particular.

Today as an entrepreneur you have more options.
