Well, really, a professional desktop is what they're missing, and features in OS X that may have been asking for, such as the latest version of OpenGL, ZFS or a suitable replacement, and better virtual desktop/window management that was crippled with 10.7. It seems as if all "improvements" to OS X are for consumers and "power users," such as Notification Center, Mission Control, porting of iOS apps over to the desktop, etc. There's been no major breakthrough since FileVault 2 was announced, and usability has drastically dropped since 10.6 in favor of kitsch like the stitched iOS apps.
