So the information for WWDC came out today (with a whopping 5 weeks notice) and it struck me, as it has many people judging by Twitter, that this year Mac OS X is the red headed step child more so than ever. To demonstrate this I went through all the sessions, of which there are 66 this year, and determined if they were just for iPhone OS, just for Mac OS X, for both, or weren’t really specified. I did this overall and by category and here are the resulting charts:





As you can see almost every session applies to iPhone OS in some way and very few apply to only Mac OS X. If this is any indication then even the sessions that apply to both OSes will mostly focus on iPhone OS. The question now is, is it really worth it for non-iPhone developers to bother going this year?
