Yah, that's the effect of today's "instant, always-on, right-now, me-too" world that we live in. I don't think there's anything wrong with borrowing ideas from competitors to improve products. The only time there is a problem is when the entire product matches a competitors. That's where this whole "who ripped off who" mental-attack started. Google and Samsung *are* guilty of ripping off entire implementations, but I think the world has evolved past that now.
