Garmin Nuvi 3790T

Pros: Navigation spot-on
Traffic decent-enough
Learns your routes
Bright screen
Detailed maps

Cons: Bad microphone
Stale POI's (at purchase)

Summary: This thing works as advertised. If you want a super-cool, light - highly useable navigation unit, this is the one to buy. For nothing less than the very fact that it can learn routes and also put you on the known fastest routes - it's worth its weight...oh that's right it's light - it's worth the $450 (October 25, 2010). Its the only GPS that can go head to head with the TomTom Go 930 for feature set, but useability blows TomTom out of the water. Sorry guys. I've had 3 TomToms, this thing is just too useful AND packs the featues like you guys :-(
