bluetooth is much slower than other wireless protocols, such as wifi. Not much you can do there. I wish we could connect via USB.

Bluetooth's limited bandwidth is definitely a weak link when used for tethering purposes. Many of the cellular wwan connections are considerably faster than bluetooth, particularly now that EVxDO Rev A is widely deployed. Bluetooth 2.0 and the 2.1 spec which recently got signed off upon offer something called EDR (extended data rate), which increases the bandwidth a couple fold, but frankly it is still not enough. Bluetooth is, imo, really showing its holes, chiefly due to a lack of forward thinking when the spec was initially designed. A bluetooth 3.0 spec which breaks with the original spec entirely would be most welcome.
A lot of handsets are coming out with 802.11 support these days. I think a great stopgap solution while waiting for a not yet extant future Bluetooth spec to solve all the problems of the world would be to be able to put the WiFi chip and access point mode to share out the WWAN connection. My guess is the FIC NEO 1973 is likely to be the first phone to support this sort of function, due to being completely open source. There are a number of companies making WWAN to WiFi routers including Kyocera, Linksys and Junxion, and it is fairly trivial to roll your own, but all these solutions are far too bulky imo. A cell phone as instant hotspot is definitely on my top ten lists of tech I would like to see in the not too distant future.

Actually the bluetooth used on the N800 is slower than the BT on my N95 or my N80 or between laptops.
In transferring the same ~1MB file to the N95 it goes in around 80kbps whereas with the N800 it's around 40-50kbps.

A Bluetooth 2.0 connection (as on the N800) has 3Mbps of bandwidth, and as such being able to transfer data at rates of only 400-500Kbps warrants further investigation.
I'd suggest someone file a bug who can provide further details if asked - maybe the Bluetooth implementation on the N800 could do with some tweaking/optimising as it's seriously under performing.

I am getting 800-900 kbps on a tethered n800-RAZR V3xx and I am right on the border of 3G-EDGE and in the house. I'm not complaining except I wish that at&t would cover more 3G area because most of the time I get EDGE.

"A cell phone as instant hotspot is definitely on my top ten lists of tech I would like to see in the not too distant future."
Now that sounds like a really cool must have gadget. Being able to WI-FI my n800 to my cell-phone and onto the web would be fantastic.
Any news or whispers of such devices???

when i check the internet on my moto V3xx i get speeds of about 3Mbps. when i tether my n800 to it and check the speeds through the tablet I get about 400kbps..
is this loss due to the bluetooth connection? is there a way to remedy this because we're talking about almost 85% loss!!!
on the phone:
on n800 through phone tethered through Bluetooth:
