[Nexus 7 General] Melarsa:
The new clock/lock screen is a step back, in my opinion. The bolding of the hour is annoying and the font is so much less eye-pleasing than Roboto was. When in dock mode I miss being able to see my wallpaper as the background and the ability to turn the clock font blue by long holding down on it. The whole style is just so anti Jelly Bean, which his weird because they worked so hard to get things looking cohesive and slick and now the clock looks so disjointed and different from everything else. The alarm screen looks worse as well, the contrast is very poor and if you have a lot of alarms it's really hard to see compared to the old alarm style. I like having home clock and travel clocks, though.

Having the widgets on the lock screen is nice, but they're too limited, and for some reason every time I turn the screen on the ugly perimeter box to the left indicating a widget is highlighted, even if I have no widgets selected. It's just less polished looking.

The ability to swipe on the keyboard is nice, but it seems like it takes forever to switch keyboards now, whereas it used to just take a moment. This is especially bad if you're switching between account profiles and one account has a different default keyboard from the other. If I switch to a different account it can take a shockingly long time for that account's default keyboard to open.

The secondary notification screen is nice, but unnecessary. Couldn't they have just added the toggles with smaller icons in a horizontal row and kept everything contained a single notification bar? It's just neater that way, less chance of hitting the wrong notifications bar. Plus there's no customization. I'd rather stick with a widget like SwithPro for my notification toggles. I can imagine two notifications bars confusing the hell out of less technically inclined people.

The user profiles is the best new addition, but unfortunately since I was one of the early adopters I was only able to get a 16gb version. If I'd had the chance to buy a 32 I might actually have enough spare space to share the tablet with another user, but as it is the tablet's almost entirely full. Still, this is the right direction to move in and I'm glad the option is there.

The day dream slideshow feature is neat, but I find it pretty funny that there's all these good-looking dock options when the official dock has yet to be released and my not ever be.

I'm not a fan of having to click on the build number over and over again to bring up the developer menu option. I was very confused until I googled the answer. This is just one more thing people who are new to Jelly Bean are going to have no clue about and needlessly clog up threads with "How can I turn debug on? I don't have any developer menu!" posts.

The tablet also seems a little buggier/slower in general after the update. While testing the account feature it got very slow whenever I switched accounts or changed a setting on one account and then switched to the other and changed another setting.

Overall it's not bad, but I question some of the design changes. Hopefully some of the bugs will get worked out soon. I really wish they'd included low-energy bluetooth 4.0 so things like the Fitbit One could sync, but so far even though we have the right hardware for it there's been little to nothing said about actually implementing it so users can enjoy that feature.
