I actually thought it looked halfway decent during the keynote. But I just put the beta on my 4S, and it's pretty hideous and just straight up awkward in real life usage. It seems even more Fisher-Pricey than ever, but more than anything, everything just felt really bloated and cramped on my tiny screen. Maybe it'll grow on me once it's out of beta and I upgrade to 5S.
I also miss having the weather widget in the notification center, and not sure what the hell happened to the Voice notes app that I use to record lectures.
I can tell YOU aren't a developer and have no business installing iOS 7. If You WERE you would KNOW, that Voice Memos isn't available in THIS beta, It was stated in the release notes. You would ALSO know that the Weather widget is in Notification Center in a new form, and the other two widgets aren't available yet.
