The first time I saw the jump in handheld gaming revenue share to iOS – it was pretty striking. There are 128 million Nintendo DS devices worldwide, 60 million for the PSP, and from what I can tell 100+ million iOS devices (yes, not all used for gaming). Google’s new app store (and investment in Zynga), will work great on any Chrome (Google) OS device. And let’s not forget Android, and the possible reassurance of WebOS.

I’ve received some great comments, questions, and kudos from my IA Summit and Big Design talks on Mobile Strategy, and I’ve heard from a good number of people that they’re using the presentation to make decisions about mobile strategy on their own (which is great!). I did put together a couple of quick worksheets that could help turn the presentation into a mini-workshop for anyone trying to make decisions about what to do in mobile.
