> Especially Google Now, while certainly interesting, seems to be useless to me so far (or I just don't get it?).

this is interesting, because for my usage, Google Now was one of the most useful additions in Jelly Bean. i use it all the time, and love the notifications about nearby public transit, time and distance notifications for appointments from my calendar and so on.

it's pretty basic at present, but it's already useful for me day to day and if they were to open the API could be dramatically more so.

> Do yourself a favor though and install Firefox Beta. Give it a shot against Chrome - for me the experience is so much better that I'd wish for a way to uninstall Chrome.

several people have said this as well, so i will definitely be giving it a shot.
