I agree, but the similarities are being pointed out precisely because Apple (and their major pundits like Marco and Gruber) makes a big deal about how others have borrowed ideas from them.
For example, the infamous "Redmond/Mountain View, start your photocopiers" lines, and Marco/Gruber's frequent quips like "Hmm, I've seen something like this before..." in regards to something Google or Samsung has done.
Apple's smugness is what's getting them, not their borrowing of ideas, itself.
