iPad Mini Scores Poorly in Teardown Analysis
A 2 out of 10, which is the exact same score iFixIt gave the recently introduced 13-inch MacBook Pro with Retina Display. In this case, the iPad mini was dinged points for having "teeny-tiny" screws that are easily misplaced if you're not careful (Protip: slap a stick of double-sided tape on your work area to hold screws and other small parts, or pick up a Petri dish), copious amounts of adhesive (front glass, logic board, battery, front and back cameras, ribbon cables), soldering the Lightning connector to the logic board, and for the use of hidden screws.

On the positive side, the iPad mini's battery isn't soldered in place, and the LCD isn't fused together with the glass panel, so both of those can be replaced independently of one another. Overall, however, you're probably better off investing in a warranty (AppleCare, SquareTrade, and Best Buy, to name a few options) if you're concerned about repairs when purchasing an iPad mini.
