Not only will you receive a beautiful website but it will also look good on someone's phone. Your website look can be different when it is accessed using a mobile device. The design and text will be optimized for the smaller screen of mobile devices, so.......
According to Pew Research Center(http://pewinternet.org):
"Nearly half (46%) of American adults are smartphone owners as of February 2012, an increase of 11 percentage points over the 35% of Americans who owned a smartphone last May. Two in five adults (41%) own a cell phone that is not a smartphone, meaning that smartphone owners are now more prevalent within the overall population than owners of more basic mobile phones."
This just reiterates the need to have your website or application designed for mobile.
This report is based on the findings of a survey on Americans' use of the Internet. The results in this report are based on data from telephone interviews conducted by Princeton Survey Research Associates International from January 20 to February 19, 2012, among a sample of 2,253 adults, age 18 and older. Telephone interviews were conducted in English and Spanish by landline (1,352) and cell phone (901, including 440 without a landline phone). For results based on the total sample, one can say with 95% confidence that the error attributable to sampling is plus or minus 2.3 percentage points. For results based Internet users (n=1,729), the margin of sampling error is plus or minus 2.7 percentage points.
