These are, I would suggest, established companies > and fairly significant market actors. I have a Palm device on Cingular and a HP iPaq on T-Mobile, both are unrestricted. I also have a bunch of walled garden 'imode' phones where I have only accessed the Web browser by accident. Walled garden does not seem to me to be a very successful business model. It means customers have little content available to them. I think that is self correcting. I know that in the MBA business courses they wax lyrical about 'razor and blades' business models. Fact is though that most attempts to establish that model artificially fail. Ink jet cartriges and video game consoles are the main exceptions. People understand the lock in effect, in most cases they try to avoid it. _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
