In some cases form over function: - Headphones out at the back. This 'issue' is solved by connecting the iMac to an amp and plugging the phones in the amp's headphones out. (While connected to an amp I now play music a lot more over my speakers, though not as good as with a dedicated cd player the sound is pretty good!) - Awfully placed usb ports at the keyboard. And finally this tiny annoyance: Slow disc reading and a drop in system responsiveness, even with 4 gb of ram, when a disc is inside, no matter if the system is busy reading or not reading the disc at all. Other than that I have no quarrels.
