The plus is worth the wait! It's just the right size when I do not feel like whipping out my iPad mini in public. I'm already acclimated to using it two handed so I do not drop it. Knock on wood. I even like my cheapo $6 eBay cover I bought ahead of time until an awesome plus case comes out that fits my needs. Glad I ended up getting one that covered the buttons, since they're larger now and seem more prone to getting damaged vs the 5s.
can you post link for the case you bought?
