There's that, but happily isn't the word. Every year I'd go on a research spree to find a replacement but it had to be as small or smaller. Every year I came up empty so eked out another year on the old phone.
I'd happily replace more often if only palm-sized or smaller phones were available. I'm not particularly price sensitive either, I'll pay top premium price to get a conveniently-sized phone if someone is willing to sell it to me.
