Well, Google Now was more bad than good. The Assistance, however, is a promise of beautiful things that already works much better. The cards surprisingly do to - they very accurately provide information that surprisingly you are actually interested in.
Sounds really interesting, but obviously it's not so easy to reach the level of FB & Twitter. But hopefully it will, we'll see.
I was reading the description and it seemed familiar and then bam - Google Now... but yeah, it's typical of Google to drop one service and then replace it with something different and then, sometimes, revive previous version...
I just completely removed Google Application /Search front eh phone because it kept constantly changing and it became a bloat without any relevant use (except for flights info) and went back to good ol' RSS where I can choose what o want to see
