Search interest in Mobile Development Platforms

I was looking at Google Trends and thought it would be interesting to see how searches for information on the latest mobile development platforms have changed over the last year. I decided to look at searches for "Android SDK", "iPhone SDK" and "Windows Mobile 6 SDK". Note that the results do not reflect the relative volume of searches between each search term. Instead, they show how the search volume for each term has varied over the twelve months. Out of the three terms used, "iPhone SDK" had the largest search volume by a factor of 10. What I found interesting was that searches for Windows Mobile were pretty much constant throughout the period. Searches related to the iPhone SDK peaked suddenly in March - when Apple announced that the iPhone would soon support Exchange for business e-mail - and again in June 2008 with the release of the iPhone 3G. Searches related to Android peaked with Google's announcement of the platform in late 2007 and again with the release of the first Android enabled handset in September of this year, but whether this interest will be sustained remains to be seen. My interpretation - interest in iPhone application development has shown major growth over the last year increasing over 6 times, while interest in Windows Mobile Development has remained stable. As for Android, there are a lot of people watching what is going on here, but I'd question how many hardcore developers this platform really has.
