Sure, but no one was making claims about actual computers other than the human brain that requires pointing that out.

Actually, it's a rather common observation that real-world computers are not Turing complete (languages, considered independent of the limitations of concrete machines, may be) and particularly that concrete machines with limited storage space and operating with finite time constraints may not be able to compute all computable results, even though the abstract model they approximate, without those limitations, can.
