The rise and rise of mobile sites

There's an article in this week's NMA about how 60% of consumers think it's important to be able to access the internet from their mobile, and 65% of those who are planning to buy a phone in the next year will be looking for a good mobile internet experience. Surely the iPhone and Twitter are partly responsible for this rise?? There are a couple of things this means for the digital industry - firstly we'll all need to make sure that the sites we build are easily 'readable' on mobiles and secondly more brands are demanding mobile-specific sites - sites built specifically for mobile access. Will it be restricted to certain sectors? The NMA article suggests that banks, sport, travel, social networking, local amenities/guides and ticket purchasing would all benefit - and having mobile access to Wikipedia would settle a few pub arguments - and make pub quizzes a cinch!
