TapRoot Systems has put out a helpful report that tries to streamline information about the increasingly fragmented smartphone market. “How Open Is Open? The Mobile Open Operating Systems Landscape” looks at the major players and announcements from various companies and segments the offerings according to their operating systems: Proprietary Closed, Proprietary Open, Commercial Open, Community Open, and Open Source.

The report is not lengthy at seven pages, and it includes graphics and tables to help present the information. It touches on the advantages and disadvantages of each of the operating system models, and while it is aimed more at the audience of vendors, manufacturers and other market stakeholders, it offers a clear snapshot of what’s happening with smartphones that might be helpful if you’re just trying to sort out what’s out there and attempting to make decisions related to purchasing or support.
