SD Times is reporting some interesting results from a recent research study conducted by Evans Data. Apparently, application development for Windows Mobile devices is sharply on the rise -
"Specifically, the study concluded that C# usage in mobile application development has surged over the last six months, partly due to the availability of Windows-based smart phones. According to Evans, 40 percent of mobile developers are now using C# somewhere in their development process.
Elsewhere in the study, Evans concluded that 30 percent of mobile application developers are using Microsoft SQL Server as their back-end database, while 20 percent use MySQL. The study was conducted this past November and encompassed 380 wireless developers."
I really don't find this all too surprising. Back in the first few months of the year, I received a large increase in the number of conversations with both enterprise and individual developers regarding the .NET Compact Framework. Time and time again, they pointed to a single event - a key decision-maker in an organization purchasing a Windows Mobile-powered Palm Treo 700w. These new owners were in many cases the same people who either didn't care or didn't believe in the power of the platform. Things certainly changed once they got their hands on a device 
Here's to hoping the trend continues in 2007. I look forward to even larger turnouts at Windows Mobile developer events.
