According to comScore, over 63 million people in the US use the mobile Internet, with 35% of those people accessing it on a daily basis. eMarketer says that over 70 million US mobile phone users will access the Internet from their device in 2009.
eMarketer also says that mobile e-commerce is still in its infancy though. While some retailers are ahead of the game, many are still "watching from the sidelines," and planning their mobile commerce strategies.
