Five years ago I think I had some Samsung phone, maybe; I don't remember for sure. Or that might have been the year that I first got a Palm Treo. I went through three Palm Treos because they kept failing.
Maybe the iPhone, or Android, or both, will still be with us long-term. Maybe not. I don't really get majorly attached to my mobile phone; if the iPhone isn't the most totally awesomest phone for me next time I get a new one, then maybe I'll get something else, and leave the iPhone as a distant memory, along with the Samsungs, and the Motorolas, and the pile of defunct Palm Treos. (For that matter, I already have my original iPhone stuffed away somewhere, while my shiny new iPhone 4 is in active use...)
