Dislike.
I hate it. The 3x3 folder size on the iPad is an insanely ridiculous decision (at the very least, there should be a setting to switch between 3x3 and full-screen).
Whether or not you care for the color scheme is undoubtedly going to boil down to personal preferences, but this is the first time I have actually been annoyed by a UX. I guess I'm just not a fan of pastels.
I would not have bought an iPad with this operating system. Sure wish I could downgrade to iOS 6.
I've been 100% on the Apple platform for quite some time, but upgrading my iPad to iOS7 actually stopped me from ordering new iPhones for me and my wife this past weekend. I won't switch from Mac, but I'm seriously considering making the jump to Android for phones and future tablets...and I never thought that would happen.
