The Mini-Z is also a half-size kneeboard. zuluworks > standard mini-z A friedn of mine uses one and it looks like the perfect compromise of size and function.Nice! I'll have to see about those.
John, other commented on this: seems a bit unusual to have a problem with a kneeboard when your knees don't get in the way. What is your set-up? One of those thin kneeboards that do little more than hold a pad and pen or one of those with 10 pockets for charts, pens, extra pads, lunch...
My solution is still in flux. I've used my EFB's scratchpad and a separate app. Works OK but I am slowly coming to the conclusion that pen and paper is superior for jotting notes, especially without looking. I have multiple solutions at this point, most of which have been mentioned. A mini 3X5: notebook (kind of small); a slightly larger 5X7" or 8.5X5.5 notebook (I like the size); and the steno pad or other 6X9 item (which are about the same size as a kneeboard (and which I've used on a kneeboard for decades before the EFB came along). But I think that, especially for IFR, any of those could use a stable platform and the basic kneeboard seems to fit the bill, although I'd really like to try out that mini!
