About time that someone did all-in-one charging for both talk and data minutes, rather than forcing users to walk a tightrope by having to keep separate track of both. This is likely to be the defacto cell services model in the near future.
I also predict that some Helio services, such as integrated Yahoo! IM and MySpace.com access, will eventually transcend the Helio demographics and become standard fare.
De rigeur not just on Helio, but on pretty much every cell phone and not long after that, on VoIP softphones and VoWiFi handsets.
I also like the "Gifting and Begging" features, which enable Helio users to buy content and then have it delivered to friends- or ask their friends to buy this content for them. I see some broader utility for other telecom brands and modes, but to me, the "Gifting" and "Begging" features sound a bit too born of how-do-we-get-these-kids-excited, focus-group-driven planning.
So let us see how Helio does in terms of uptake and execution. The broader telecom universe will be watching.
