Its quite evident from many news sources that having a specific website aimed at the mobile market may well become essential for some website owners.
As reported by the telegraph on the 10th February Smartphones are now outselling desktops.
"worldwide, consumer electronics makers shipped 100.9 million smart phones in the last three months of 2010. This is up 87 per cent on the same period in 2009. PC shipments rose just three per cent to 92.1 million."
Google also say
"For now, we expect smartphones to handle desktop experience content so there is no real need for mobile-specific effort from webmasters. However, for many websites it may still make sense for the content to be formatted differently for smartphones, and the decision to do so should be based on how you can best serve your users"
Other research by Google has shown
"71% of smartphone users search because of an ad they’ve seen either online or offline; 82% of smartphone users notice mobile ads, 74% of smartphone shoppers make a purchase as a result of using their smartphones to help with shopping, and 88% of those who look for local information on their smartphones take action within a day."
So should you serve different content to your users? It depends really on what you do and how people interact with your website. If you have Analytics installed you are able to see what the growth is of mobile devices accessing your website. If the trend were on an upward scale then it is worth investigating further.
If you run an adwords campaign, do you separate out your campaigns into desktop and mobile?
According to collected data Mobile searches have grown by more than 4x over the past year and by 2012 more people will connect to the Internet via a mobile device than through a computer.
The evidence is there, the choice is yours!
