Hi,
I found a website that may or may not be of use to anyone and I wanted to share it. I don't know how accurate it is, but I would think it could give people at least an idea about the device market share and stats about them in a selected region or world wide. I have not researched it extensively, but the little time I did it gives market share stats on types of devices such as mobile including tablets and desktop from everything like display sizes, operating systems, browsers, search engine host, Windows, MacOS, iOS, Android, Linux, etc, etc.
You can click on items in the legend to add or remove to get a better idea of where something is at if there is a cluster of items in an area on the graph. You can page down and select what type of stats you want to see. It might help people to decide what market to target even get an idea about majority screen sizes and so on. I know it can be hard deciding what screen sizes to target in you programs to be able to cover multiple devices with each program you develop.
