Proudly NOT addicted to my phone. I got a new one in January and the sales guy thought I was insane to get a two year old model. I have to this day not even fully explored it so I am blissfully unaware of it's features. It has buttons, and I like that! Damn those touch screens!!
Only one thing has been the same since I started using a mobile phone: my ringtone. Just love it. It's the phone-ringer-sound at CTU from '24', such a compact and cool frequency.
