I'd like to point out that an optical drive doesn't sit there spinning. Not having one won't give you a minute more battery life vs having one and not using it.
What I don't get about Chef's post is that he wants a
12-13" tablet. Why not just have 12-13" like we already have, which HAS a keyboard, rather than carrying around a bluetooth keyboard and optical drive "incase you need it". Sure it will be thinner without those two things, that is why I agree with the last poster about only saving 5mm or so by removing them, so I think they should be there.
iPhone is your tablet.
So what I gather is that these "people" you talk about want a 13" inch macbook, without half it's connections, less storage, no keyboard or optical drive, 'oh n0es no wireless docking, must be wired'. Yeah it would be fun to play with for 5 minutes. Until you realise you need a dock, a keyboard, an external drive, etc for the $1000 POS you just purchased.
As for saving weight, wha? They are light enough as it is, but yes they will get lighter. If something comes out, it will be 11" and will most likely have a keyboard and optical drive. Why? Because fingerprints suck
