AdMob: iPod Touch Now Second Largest Device on Network

I purchased an iPod Touch because I wanted the mobile Internet, apps and related functionality of the iPhone but didn't want to switch to AT&T. It would appear that many other people made the same choice according to the latest AdMob mobile metrics report (released last week):

The iPod Touch is now the #2 device in the AdMob network with 4.7% share. Combined, the iPhone and iPod Touch represent 15.5% of all worldwide requests.

Here is a high-level overview of the data (AdMob's summary):

The iPhone and iPod Touch have grown steadily, obviously. But so has Android. That will be even more true when multiple new Android devices hit the market this year. RIM, which generally offers a poor Web experience across most of its handsets, and WinMo have suffered at the hands of the iPhone, largely. Look in particular at the Worldwide OS chart above. Symbian, the smartphone incumbent in Europe is losing share. And WinMo has a relatively small share (<10%) in Western Europe. RIM's European share is even smaller.

These numbers don't necessarily track 1:1 with overall market share but they're representative of overall mobile Internet activity.
