I'd like an App Store with a "if you delete it within X days you get an automatic refund" model. That would make buying apps risk free and refunding them hassle free, without the annoyance of having "Lite" vs "Full" versions.
The failure of that model are the apps which provide only short-term functionality. e.g., I'll probably only need my offline map of Brussels or that puzzle game for a few days. But my being through with them within 96 hours doesn't mean I'm entitled for a refund-- in fact, they probably served their purpose! Such a refund model would rob developers of that niche.
Doesn't Google Play work like that? The rebate period might be a lot shorter though, perhaps even minutes. I think they started out with a day but it was exploited too much.
It is 15 minutes now. (Which is far too short to even begin to use a lot of apps like games that download tons of additional resources without mentioning it in the app description.)
