I humbly think that having an ODD right now may in fact matter to the average consumer.
I was at my local BestBuy about 2 months ago & was playing with the MBP 17" demo set when a young mother with 2 kids (I assume they are middle school kids from their height & very youthful looks) came over to check out the Macs. The mother was looking at the iMacs while the 2 kids were happy marveling at the new MBAs.

One of them called her mom over to check out the thinness & lightness of the 11" MBA. The mom came over picked it up with a "disbelieving" look, look around the length & width of the MBA & told her kids "What?
This is not a good computer, there is no CD drive! Let's look at other computers." She then lead her kids over to check out the PC notebooks without even checking the rest of the MB/MBPs!

I assume that she must have thought that all Apple computers do not come with optical drives after seeing the MBA without one!
I know this is something you guys may find funny &may probably laugh at the stupidity of that mother but that is actually what really happened that day.

I'm pretty sure that family is not the only one with such reception to the lack of optical drives in notebooks as of today, even though in time, everyone will embrace the idea of having notebooks without an optical drive.
