I don't really understand what the selling point of the newer models is. I'm also quite happy with a HTC Desire (apart from the internal storage running out of app install space, had to install CyanogenMod just to patch over that), since it seems to do everything I want from a thing with that particular form factor and interface constraints. Basically, browse the web, write short messages, display reflowing text documents, run a scientific calculator and play video and audio. All of these seem to generally run without me thinking "I wish I had more processing power for this".
