Wow I guess Google want's to pound me over the head with Nexus goodness to ensure I never even
think about leaving my N1 again!
Just installed 2.2.1 from Android Central and have to say it is another stellar update.
Not as big of changes as something like Froyo or Gingerbread but after having the update on my Nexus I notice the following 2 things:
1. Nexus One is faster overall

2. WiFi dropping while sleeping issue is fixed!!!


The WiFi issue was the last thing that kept the Nexus from being absolutely perfect and now Google fixes it 2 days after I come back.
It's really hard to accept Google, T-mobile, and HTC customer service as real. Most companies I've had in the past have always delayed updates or never fixed problems. With those 3 companies and their stellar customer service I have to say that this phone is the best I could hope for.
I've already flirted with a 4.3' screen and learned my lesson... I will
ALWAYS use a Google developer phone from now on. Period.
