Of course, if the dimensions are different for an iPad 5, there will hidden costs like paying for a new case instead of swapping out and using a perfectly good me.
I rarely hold any of my tabs. I like them at eye level and prefer to be hands free. I have a couple of stands, but my hands down (haha) favorite is this one:
Amazon.com: LEVO Deluxe iPad Floor Stand for all iPads Galaxy Xoom Nook and Other eBooks and Tablets: Computers & Accessories
I can make it hold an iPad and a Kindle Fire at the same time, plus a Jambox BT speaker.
