A mobile development dilemma
We know instinctively the time is now to take mobile seriously. But as your prepare have you considered what exactly you're preparing for?
A mobile app or mobile site?
Though mobile site browsing outnumbers app users, those app users consume 2.4 times more impressions! So what do you do? This infographic is useful if only to reinforce how serious you need to take it the question.
We'd suggest that the answer may be around what are you using mobile for - recent research suggests that apps are more about accessing data and connecting with others, especially where leveraging the phones native services (like geo-location) are important. Mobile sites on the other hand are proving more popular for shopping and entertainment, for now.
Also remember that from a pragmatic perspective, it's going to be cheaper to try and test via a mobile site. Food for thought!
