Not sure what you mean here, but if it is the possibility to start your own WLAN, thats just a fingertip on any smartphone these days.
Actually, thanks to the barbaric American cellular service providers, it's still somewhat uncommon over here. They charge an arm and a leg for it, too.
When I was choosing my first smartphone, my choice came down to iPhone or webOS. I did ultimately go with the iPhone, which proved to be a good choice for the commercial longevity of my platform. But after webOS melted down, I was able to pick up a few devices on the cheap to play around with. The UI is incredibly clever, and the Synergy connectors are brilliant - sort of like Datatypes for communications. i.e., no need for separate clients for all your various providers - just get a Synergy connector and then your generic programs (email, chat, video call, filesystem, etc.) will all work.
Everyone said the webOS phone hardware was underpowered. That may be partially true, but I think performance could have been vastly improved if they had been able to tighten up their code. I hope the TV line is successful enough for them to try a phone again - it looks like things have gotten much slicker in the intervening years. I'd get one of the televisions, but I just bought a TV a few years ago, and it'll probably be at least another 5 before I'd consider replacing it.
