Why bother.

Two other incarnations are due out and 8 - 10 months seems to be the frequency.

Each time another one drops, retailers deep discount the previous version to make shelf space I suppose.

Even if the WiMAX version turns out to be a Sprint exclusive, knowing how the US Cell service providers operate, it will have a $150 - $200 subsidy discount for a two year contract commitment.

This version is not for existing N800 owners. As stated elsewhere, an itty bitty slide out is no substitute for a BT keyboard and for under $50 you can always add a BT GPS receiver that can be positioned independently for the best reception.

Besides, it seems to be positioned for head to head competition with this Christmas' market for in car navigators which is expected to be huge in the US.

Why pay $500 for anything that is "just" a navigator.
