Good to see people talking about this case. I just got this last week too, and I am overall impressed by the quality of the print and design. Didn't see too many festive designs around this time, so it's cool to have my iPad mini be in the holiday spirits are well (it's part of the family ). I went with the Little Trees because I really liked the pop art style it evokes.
This case is very similar to Poetic's other case for the iPad, the Slimline series. There are some marked differences, though. The cover feels less like the leatherette on the Slimline, and it doesn't have the microfiber on the inside as well. But the rubberized hard shell back seems tougher, with a soft touch feel as well. The triangle stand works REALLY well. There was no break-in period, the cover was snappy and sturdy right out of the box. And of course, you have the Christmas designs. I recommend it if anyone is looking for a bit of holiday flair for their iPad mini case. And yes, the penguin one looks adorable.
