As for alienating the 7 million people, AvantGo will probably reign supreme for a long time to come. They have the easy way. In order to run iSilo, one must get the address of a mobile site, which we all know is not always made obvious, or even publicly available.

Further, one has to set up the channel, deciding the proper link depth and choosing all the other settings. All of this activity requires time and some knowledge. Those are two things that most users are not willing to offer. People at large, the non-nerds among us, often want the easy way, just click the add button and make the content appear. No typing, no setup, no time required. AvantGo offers exactly that kind of convenience.
