Correction - the old apple keyboard works. Originally it didn't, but it was paired with my notebook too at the same time so there may have been hiccups.

There is also a fabric bluetooth keyboard (from elec tex, google it, xtreme-geek has it too), but the reviews have been mixed - it is nothing like a tactile keyboard.

For me the iGo is adequate (but having to do the blue Fn or green Fn all the time is taking some time to get used to).
