The best current social-networking device, the Helio Ocean, takes the T-Mobile Sidekick concept to the next level. It's about staying in touch through every possible means, and it integrates e-mail, IM, phone calls, MySpace, and blogging in a way we haven't seen on any other device. And if you're willing to trust that Helio will make the device more powerful over time, it's a fabulous communication tool.
