This sounds like a cool tool even if it's not one I would personally use. TeleFlip lets you receive your emails as text messages for free (unless you don't have unlimited text messages from whatever company you have - be careful with that). This would be a great tool for someone that travels a lot without a computer.
Personally, I've never been big on phones with web access. Part of it's that I'm a penny-pincher and I hate paying for things I don't need, but mostly it's that I don't want to turn it to one of those people. You know, bluetooth headset, obsessively checking email, running around frantically. I like having a normal life and online life that are separate from one another.
