I've had Nexus One for a while and am confused about the bad press. I don't have any connection problems of any kind. I can see the screen in bright sunlight if I turn the brightness up, although it's a bit dim. I haven't seen any slowness, but I guess I can see a very slight delay in finger drag response, which some have called unresponsiveness.
I can pinch-zoom (yawn) and look at my Exchange mail (yechh), two features iPhone owners complained were missing that no longer are.
I have OTA updates and OTA software installs, wallpaper and live wallpaper, customizable home screen with widgets, the ability to run more than one app at once and the ability to run background services if I want. I can also perform voice guided navigation powered by voice recognition search. As far as I know, iPhone users can't do any of those things.
