I'm with those who rue the ever decreasing numbers of CD cases these days, for all the reasons already alluded to .. better protection, easily replaced, spines legible end on in a rack, etc.
My copy of Drones by Muse is in the digipak format, by way of a 3-page gatefold with inserts all over the place to contain the CD, DVD and 20-page booklet. Problem here is that you have to be careful opening it because the slots are all open ended, so stuff can easily fall out if you're not careful. On the plus side, at least the digipak in this instance, when closed, has a similar spine width to a CD case, so I can locate it easily enough when it's in storage.
On the subject of the booklets that come with CDs ... in the days of 12" albums the artwork and the booklet information were a joy to pore over while listening to your fresh vinyl pressing for the first time. These days you need the vision of a raptor to be able to read them at all, especially as sometimes they use some arty-farty script into the bargain which just makes things even harder!!
