When a new product comes out, it takes 6-12 months for production of accessories to ramp up, by which time you already have something that works (rather than something you’d love to have) and you’re approaching a new product release (which will change the device’s form factor). For example, iPhone 4 cases… MacBook cases… iPad cases, etc…
I love my MacAlly faux-suede Bookstand iPad case… I worried about ordering them sight unseen, but I couldn’t have been happier with mine — it has provided great protection and no fuss. It gives me access to all the ports and gives me comfort when I put the iPad into a bag.
Yet, if these two things had been out at the time, I might have gone with the combination of them, instead:
I don’t whether I would have liked them better or worse than the Bookstand, but I like the idea of them.
