it would suck if we had to pay yet another carrier fee with this device. i think most who already have iphones would not want to shell out another $30-40/month for data for this device. i hope it has free data like the kindle's whispernet...at least for the first so many MB. this would make it easy to download the news and some books and apps...
I'll just say it right now: a carrier fee will be the kiss of death for this device. From the New York Times article I quoted above it just mentions a persistent 3G connection....so here's to hoping it follows the way the Kindle is.
