As far as I know there isn't anything that competes with the NIT that makes Nokia want to drop the price. If someone wants a portable laptop they'll get a netbook. If they want a music/video player with nice apps they'll get the ipod touch. If someone wants an open source device to play with and has features no other device has then they'll get the NIT.

Sony's Mylo 2 is the nearest competitor to the NIT. Compared to the N810 it runs for $200, has a better camera and 1GB memory built in. Too bad it isn't open source, is a little bulkier, uses Memory Stick instead of MiniSD, and has no GPS or bluetooth. For some people the $150 difference isn't worth the open source GPS and bluetooth, for others it is.

As for UMPCs: Those things are crazy expensive compared to a tablet. They are pretty nice though. If I had the money and if they were smaller I'd buy one instead of a tablet.

The devices pretty much match the buyer's personality. So go buy whatever you want and stop bickering.
