What can we learn from the mobile market?

We all know that the mobile market is making tons of money but how and what can we learn from them. Well for starters you can pick up just about any mobile phone and make a call you don't have to learn a new interface or anything just pick up the phone, dial, and push the send button. In the PC world if I just wanted to browse the Internet I may have to learn a new interface or do something totally different than what I'm used to. Ok now say you want to get a new ring tone for your mobile it's really simple to do all you have to do is to subscribe to a service and download your ring tone which is automatically put on your bill you don't have to provide your credit card number or anything and if you didn't find what you wanted you can just subscribe to another ring tone service. Then again on a PC if we wanted to download a song to put on our ipod we'd first have to install itunes then fill a out lengthy form to give away all of your private information, then if you didn't find what you was looking for you would have to find another download service and fill out another huge form and give away vast amount of your personal info to another company. It's no wonder why the mobile phone market is doing so good it's because mobile's are easy and fun to use there's no hassle to get the latest browser or download the newest software. Mobiles just work and they work well under all conditions. We need to take this into account when buliding a web site our sites need to be fun and easy to use and require as little personal info as possible.
