I can understand the frustrations: you buy this to find the packaging is awful and is not going to protect your already expensive collection, but lets look at the reason why this is a good DVD set to own.
For a start, it's really well illustrated, plenty of pictures, and fun packaging. OK it's not easy to get the disks out, but it's functional. The season 12 book is cool too, comic book like and has plenty of information you want to know about the series.
Secondly, this is still a funny season, episodes like HomeR where Homer finds he has a crayon in his skull, and Worst Episode Ever where Comic Book Guy finds he fancies Skinner's mum is also very funny. Lisa climbing a tree for a boyfriend was also quite a funny moment too, so yes, there's plenty here to enjoy.
Thirdly, extras, I love the Comic Book Guy: Best Scenes Ever featurette, where we get 9mins of the best Comic Book Guy moments, "excuse me, no banging your head on the counter please", he's just such a dysfunctional geek; but that's why we like him. I also like the fact there's deleted scenes and plenty more fun to be had with this after the episodes have been watched. In total, I have enjoyed 4 nights of 3hrs or so watching this, so it's worth every penny.
OK, the packaging is bad; it's expensive, but it's a good show and I know I will come back to this time and time again, the show was starting to go slightly downhill, but if you love The Simpsons like I do, you'll know how great each of these episodes are. Having the tactile head version is cool too, but not easy storage wise.
I highly recommend this, though Fox, please make the DVD storage side of this better please! We don't want to scratch our pride and joy, our Simpsons DVD collection.
