Just between you and me, I'm not a native English speaker, had never even heard of a dessert called Ice Cream Sandwich and only belatedly realized it was a piece of software.

If they'd simply call it Android version x.xx there would be no problem at all.

The only other arena where I recall come across such silly names is when people name their horses.

Who RMS is is important enough for me to remember, I couldn't care less what each android release is named because (1) I don't have an android phone and (2) I don't develop for Android.

Saying that it is just a dessert name and that I'm supposed to realize that is the same as telling you that you should have known that Grießbrei is a dessert too (and that one at least roughly translates). There is no equivalent to Ice Cream Sandwich in any other language that I'm aware of.
