My email and I have a love/hate relationship. As much as I love keeping in touch via email, I also feel an "obligation" to check it all the time, and it can interfere with my life sometimes. Overall, staying connected is a net positive though, and my iPhone certainly makes it enjoyable and efficient.
Mobile Email for the Non-Geek
What about the "rest of us," though? The non-geeky crowd who might not have ever even used a BlackBerry or iPhone, clutching their Moto RAZR's and entry-level Samsung candybar phones that they got for free years ago? The folks who really want to stay in touch with their kids and more wired friends and family members via email, but avoid computers like the bubonic plague or door-to-door pamphlet peddlers?
