Okra!
Yes, I know the version names of the past have been desserts or sweets, but this is going to be a new, leaner, meaner, and healthier Google.
Unless Google does something unique and partners with Oreo or licenses the name I don't see that happening. Besides, it would be odd to market Android in Oreos commercials and vice versa.
How about just "Orange"?
Oranges are sweet (and sour I guess)
But people might get confused and see it as another insult to the current president...
Maybe "OJ" (Orange Juice)?
Actually, maybe not "OJ" just to avoid any confusion with OJ Simpson...
