Why not wi-fi ad-hoc networking between the n900 and the n8xx instead that bluetooth?

That would also work, but drain the battery a lot more than bluetooth (no power saving in ad-hoc mode).

A mobile computer should have usb host.

*sticking with my N810*

It would be on just for the time of accessing those files on the usb stick, so hopefully the drainage would be minimal.

All these workarounds are kludgy at best.

Damn'... I need a real n900 to convince it (with the use of force if necessary) to do host mode

That Pandora I ordered in march and canceled last week...

it's laughing and pointing at me... swinging its full-size usb plug-equipped butt...

because wifi on its own is just a carrier of protocols?

bluetooth on the other hand already has protocols for file transfers built in, and more.

oh, and was there not talk about using a wifi radio to carry bluetooth traffic when speed was really important?

how about this:
take the mifi variant that has a micro-SD slot, replace with (or add alongside) a full size USB-A host port and bluetooth over wifi...

no usb host also means no external usb wireless stick, no usb ethernet adapter, no usb keyboard, no cf cardreader and that's harder to fix ...

I'd like to understand why exactly the hardware doesn't allow otg.
Not that I'm sure I have neurons enough to cope... But if somebody is going to explain I'd be grateful.

Absolutely!

this is a PHONE, not a mobile computer, nor a continuation of the NIT line.

accept it everybody! I have. sticking with 810 til something with form factor appears that substantially upgrades it in performance.

otg is one thing, true host is another...
