Thats not an argument, its just the possibility for any further discussion.
Thats also no argument, as it reads a could. It means that instead of producing 13-15 layouts Eve has to provide 26-30 layouts. If they can pull that off - nice! Just do it.
Guess what - thats neither an argument as there will always be people who joined in later and had no chance in the poll. And why just so few took part in the original poll - no one knows.
This is your first argument, nice. And what it basically says is: "Those who pay more for the device should have more impact on the design than those guys who just bought the lowest model". I call this huge bullshit. Sorry to say, but giving users in a community more rights based on the money they spend is just wrong.
Sure, and thats why iKirin asked to translate it into every language, so for germen it is "Ups" or "Hoppla". Sounds weird, yes, and maybe thats why many left the original "Oops".
Bottom line: You have said nothing new that I didn't read already a few month back. But good I read it again, just in case I forget it...
If there is an easy and cheap way of supporting people with a normal backspace key I'm happy Eve does so; the more of the community members are happy the better. But if there is not such a way, then stick to the decision we already made!
