Correction- Wikipedia said he was employee number 3. He's still not a co-founder, however.

Intel was founded by Gordon Moore and Robert Noyce. I think Andy Grove was employee number 5.

Since the "normal workload for an ultra-portable" isn't that much anyhow like you've said, then the performance difference is moot because it's not that big of a gap anyways. ...and by the same token, who in the world is going to use "ultra-portable" as "desktop replacement"? Pbbt.
