My n810 HAS replaced my Averatec small, lightweight notebook (3715), except for developing for the Nokia. I have a Cradlepoint 350 EVDO router with a UM-150 and a battery pack, so I have a pocket access point that goes with me when I'm not near a hotspot. I've used it with the laptop, or just plugged in the EVDO modem, so it changes things a bit, but it is not unlike having a phone with internet access you can pair with via bluetooth.
