Love all the negative troll comments but...
As someone who's actually using iOS 7 (along with 4.2.2 Jelly Bean) I like it - It's a marked improvement - I've handed it to non techie friends and they've picked up most of the basic changes within minutes.
Being a beta there are a few things that don't render super and a few hangs but it's pretty polished.
I wish Google would put a bit more (project) buttery goodness into 4.3 as 4.2.2 on my Nexus 7 is not as buttery as I'd like it, even when rooted and O/Cd
Funny how so many negative comments come from people who have no first hand use... Smells very hypocritical to me but I digress -
