I think I will prefer the search function in place of the caps lock key as well. It just serves a more reasonable function. I have probably only used the caps lock key once on my new laptop but I have used search more times than I could ever count.As for caps lock...I much prefer the search function that Google assigns in place of the caps lock.
I've never used it either but it sounds functional. I don't need a caps lock so I'm content with what I hear about it. I'm excited to use one though I'm picky about keyboards.I've never used the Google keyboard myself but people seem to think highly of it, certainly it sounds like a more functional experience.
