I actually tried eye-fi for a short while, it's ok for for quick snapping (aside from a few quirks), but...

• 4GB max size

• Slow. Really, you don't want to be transferring several gigs with it

• 150$+tax/duty (can't use the cheaper ones as they don't do RAW or Ad Hoc mode)

I'm ok with the host setup (actually mine is a bit simpler as I don't use a HUB but a powered drive) because it was 3x cheaper than the cheapest netbook at the time. As easy as that, no religious hatred towards netbooks (though if I'm lugging a netbook with be, I might not really need a Maemo device for the task...). Also, for some reason transfers where the N810 is the host are a lot faster than when it's connected as mass storage, but that might just be me, and with the extra grunt of a cortex might not be an issue an all.
