first impressions were that it definately does some things great right out of the box and that a huge world of options were out there for anyone who wanted to learn about them. Being really busy during the holidays, I hadn't had the change to get into it much. Here's a quick example of how much this thing has rocked for me in just the short time I've had it:
wife called to say heat in car wasn't working. I hit the n810's google bar to get some articles about why and learned about the heating components. I froogled the part to see makes and prices. I local searched the part to a nearby autostore, gizmo called to see if it was in stock, and used maps to get directions. After arriving at store, they couldn't actually find it <critical misstep not asking by phone for them to touch part>. I used their website to see other locations, show picture of the correct part, check other autostores. They called to confirm part in stock at next nearest store and hold for me. I walked out door and used GPS to drive to other store. Used net to review tools required and view install procedure while upside down under dashboard (no laptop would fit there). Listened to internet radio. $30 and 3 hours total to aquire and install, heat works in car; wife very happy. Next day I called local autorepair shop to check= $400 saved. Wife no longer gives me any crap whatsoever about how much nokia toy cost. note to self, do not have a beer with neighbor before being upside down for an hour.

it ain't saving the world yet, but it's really cool.
