I was wondering if it is worth getting the N810WE as a backup to the N900 & how well the N810WE works as an all-around device assuming one is in an area with good WiMAX coverage (I am). Also, can the device tether to any other Bluetooth-capable phone (I'm thinking BlackBerry 9700 & Nokia N95-3 in my particular case) with Internet connection & piggy off that? Finally, I did a quick eBay & Google search and was surprised that this thing is going for more than the N900 is going for!

Is the N810WE that rare or is it a very good device compared to the N900?
