So nitpickers might point out differences but you cannot deny that the basic tab looks just like Chrome's. When Chrome came out with this it was new and innovative. Now it looks like a copy. When this blatant copying happens (and it happens in many places; it's no wonder all phones look like a variation of the original iphone) I always wonder if the designers really did convince themselves that their design is differ…
The thing is: there are UX patterns that are better than others. That's not copying, it's just common sense.
