They&#x27;re expensive. I swapped my iPhone for an iPod touch because my cell company (SoftBank in Japan) kept finding ways to raise my bill with one hand while making my plan <i>worse</i> with the other.<p>That, and I got tired of people calling my personal phone with their computer problems all the time. Not the fact that they called me, but the panic and urgency at their end. It was exhausting.<p>The same deal with Facebook etc. At least without a phone you have a reason for not paying attention every waking moment.
