This Interview with the CEO and CTO of E28 is fascinating to me. You might not have heard of E28, but they are a chinese daughter company of one of the established Taiwanese designer/manufacturers, and have deals with others in Taiwan. Taiwan (and probably mainland China) is the present and future of mobile phone design, and they are heavily into Linux.
I look forward to seeing these open APIs one day. I'm particularly interested in how they integrate/abstract the various implementations of the various proprietary audio and video codecs, which probably all need to be licensed individually.
