I took the iPad 2 on my trip to Tijuana as it has the cellular, which I needed. Wish the mini did! This little machine is terrific, and much, much less to carry. The screen is fine for viewing pix or reading, and it's much more hand-holdable than the standard iPad size and weight.
I found a case for it ... The Moshi Versacover. Translucent plastic protection for the body of the iPad with a flexy magnetic cover that is designed to fold into both horizontal and vertical orientation stands. It's like the Apple SmartCover with body protection and a more versatile cover flap, keeps the mini small and light but with good protection. (I see Moshe makes the versacover for the regular size iPads too now...)
So far, very pleased. I'll likely order a mini with full kit memory and cellular soon.
