surely the sony LED screen on the new desire's puts it right out of the running for you lot ?
nexus one has to be considered over it. oled screen , less hassle to upgrade for everyone , noise cancelling , generally just better support.
Nexus One has stock Android which isn't as good as Android with Sense UI.
Email client on stock Android is terrible, stock contacts application is far behind Sense's, Sense's camera application has more features and settings - this is to name just a few improvements HTC have put in.
Better support? Did you not see all the complaints about there being no Google support when the Nexus was launched?
