Actually, I politely disagree. I think the Oops button has so much EVE-ness in it! Yes, the Eve-V is super-classy and just eye-melting to see, but remember the community has a "revolutionary/rebellious" spirit at his core: at the very beginning, some of the Pyramid Flipper project mottos were "No Bulls**t" and "Bottom's up"... (Side note... Truthfully, I hope that revolutionary spirit is still there in the Team, albeit a little concealed for marketing reason! Eheh )
Having said that, I understand that someone might prefer or even need a classic (booring! , ok jokes, I seriously understand) back key. I hope they can be granted their wish, especially if they are willing to pay a small fee to have that feature.
However, I would also understand if the Team wanted to make it a distinctive feature of the V.
