I guess, so far, I'm the only one here liking (or at least, not minding) the new 4 by 5 layout. It seems a little inconsistent at times because some app icons seem a little low-res, but I'm sure app devs will fix that sooner rather than later. Also, the one tiny annoyance I have with the new launcher, is the missing app drawer Play Store icon on the top right. I really got used to that. Oh well, something's gotta give.

Ok, found one glitch. I'm unable to activate Google Now from the lockscreen with a swipe up. Google Now does open in the background, but I have to manually unlock the phone for it to show.
