I don't have a BlackBerry or whatever you call it. And there is something to be said for being isolated and out of phone range, because you can fall into a habit to such a degree that you don't even realise that you've lost something: silence.
I hate technology and cellphones. I hate having to have one all of the time. I don't tweet or buzz or bing or whatever! It's a conscious thing - I hate the way that it can take over young people's lives.
You should not be a slave to your telephone. The technology is there to serve you, not the other way around.
Everyone who uses their phone on a day to day basis just be careful with how much you're consuming because it can get unhealthy quickly.
I have an iPhone, too, but I use the Blackberry more because I'm addicted to BBM'ing. I'm also on Twitter 24/7 and it's a lot easier on the BlackBerry.
I realised I had an issue with my mobile phone use when a friend started explaining the virtues of the Fast 800 diet and, while still engaged in the conversation, I pulled out my phone and ordered the book before they had finished their sentence.
I spend a lot of time on my phone, so I have two Mophie backups myself.
I am attached to my Blackberry. Sometimes, when I'm holding it, my other hand goes to my pocket automatically in search of it.
The mobile phone is very dangerous. If you're walking and looking at your phone, you're not walking - you're surfing the internet.
