As a learning Dev myself, you spend so many hours testing and being wrong to get it right. i have spent hours adjusting things ive built for the x and i dont even own one, just bc people asked. i could have spent that time learn on my d1 and used it myself. and still made no money. if you want to ask for something that a dev isnt doing currently and for a device we dont own, yeah expect to donate a good amount. 1. so we can get that device or 2. so we can get and pay for stuff we need to continue developing, aka a new computer or upgrades. I bought a brand new laptop a few months back just to be able to compile from source with out my computer melting down! just a thought for anyone saying devs shouldnt ask or do something just for money.
