Indeed.
If you want a POH for your aircraft simple download Goodreader and then order, or scan yourself, a PDF version of your aircrafts POH.
On my Ipad I have Goodreader with searchable PDF versions of POHs for C195, BE36, C414 (soon), my C111 A/P, my KLN90b GPS, my Garmin audio panel, as well as all my airline and Boeing manuals for the 767 and 777 - and on and on.
Thats a pile of manuals and user guides you could not see over in a tablet that weighs < 1kg.
Ozrunways is awesome - if you have too many ancillary functions you will wreck it.
By all means tweak the NAVIGATION and CHARTING aspects - but don't try and tweak it into a replacement for a brain.
