Um, I think the original question is strange...

When I stumbled across the N800 in October 2007, they were typically selling for $380 - $420. Then, almost overnight, the N800 dropped rapidly in price, and finally stopped somewhere around $230-ish, stayed there for a couple of months, and then it completely disappeared.

So, since you can't even buy a new N800 anymore, it's tough to compare prices. And the N810 is selling for about the same price now that the N800 was selling for 8 months ago ($360 at Buy.com).
