I have a Gumdrop Dropbox on the iPad 2 I let my 5 year old grandaughter use. It gets dropped frequently. She hasn't been able to defeat it yet. One thing I especially like is that it has a built in screen protector so I don't have to worry about sticky fingers or spilled drinks.
I use either a Blade-Tech Belt Holster with Tek-lok or a Bianchi Paddlelok. Both are nice OWB holsters for southpaws. I use the Bianchi when I want auto retention.
