I finally bit the bullet and upgraded my iPad 3 to a new iPad Pro.
I've skipped the Air series and haven't upgraded before this for one simple reason. Nobody is making a portrait easel case anymore. I've have, and loved my Marware Eco-Flip for my original iPad and then an updated version for my iPad 3.

Since then I have never been able to find a portrait mode case other than the bulky 360 degree easel cases.
The iPad Pro screams out for a less bulky snap in version of something like the portrait Eco-Flip case.
For now I'm going to go naked with some egrips on the back, but I really hope some vendor sees the light and realizes portrait mode is a real thing.
