I've been using a Smart Cover for around three months now on an iPad 3 in conjunction with a devicewear union shell and have found the combo growingly inadequate for my needs. I need a case that a has a few good viewing angles for use as a second screen with my laptop. Quite honestly, the iPad smartcover only has one useful angle (typing) which doesn't get me that far in this case. Does anyone have a recommendation for folio under $30 that isn't too thick but will hold up to abuse?
