Really? Why?

Yes, someday I will get a new phone. But not now. My previous phone was an iPhone (first generation); I used it until its battery began to die. It lasted me a good, oh, four years I think. Probably would have been longer if it had a replaceable battery.

I have enjoyed my N900 far more than I ever did my iPhone, and I've only had it for about a year now. I see no need to plunk down hundreds of dollars on some piece of incrementally faster hardware. Moreover, looking at the options available, it seems to me that the smartphone market is imploding -- there is, today, pretty much nothing but the iPhone and a whole pile of wannabe iPhones (even the N9 has succumbed to the iPhone clone sickness). Why would I want to switch?

Nah, I'll hang on to my N900 until it actually begins to fall apart. If nothing like it has appeared by then (hopefully some years into the future), I'll just find another used N900 to replace it.
