I guess it would take sometime before we replace the notion that we are used to in Microsoft. For example, Microsoft Office is replaced with Google docs, but what about the fact that there is no CAPS lock button?
I've seen some people use caps lock even when typing just one capital letter - mainly older ladies who learnt to touch type on mechanical typewriters that required some force to hold both shift and a letter at the same time.
If you're not one of these people, then it's unlikely that you'll miss the caps lock key. I've had my CB for a month or so now and have barely noticed that it isn't there.
IIRC there is a way to reconfigure the search key as caps lock if you really feel you need it.
