Tablet Friendly Websites – WHY?

Year 2011 has been the year for the tablet as an increasing number of users have begun browsing internet on tablets like ipad, amazon kindle, etc. and many companies have conducted surveys to find out what is the effect of tablets on internet browsing and online shopping behavior. These surveys showed how people are getting addicted to use tablets (obviously majority is iPad users), and different people have different reasons for buying these tablets. Some of them like it to use for gaming, music/videos, others like to use it for emails, social networking and last but not the least are users who are using their tablets for online shopping.

So what these studies actually show to webmasters, web marketers, and business owners???
