Depends on the device I imagine. Way back in the olden days I remember pulling my NES along with a handful of games down from the tv stand because I caught a controller walking by. When Xbox introduced the break away cords it was a Godsend in our clumsy house.
YES. So many good apps that get abandoned. Donations are all well and good but I suspect they only really pay well for the high profile apps. If a paid app will keep a Dev motivated to keep it updated I am all for it.
Subscription apps can go fuck themselves though. (Charge me for the upgrades instead).
