If you've downloaded the latest version of iTunes (10), you'll notice a small (but ever-so large) difference. The app's logo/icon has changed. Gone is the ever-familiar CD and musical note combination, replaced by a musical note with a candy-like button background. Here are some other details I've noticed.

• The app itself has changed and has received some updating, most-noticeably the icons that line the left side navigation are now monochromatic.
• The volume slider now sports a nice, round metallic knob as the contact-point. A small detail, but I like it.
• The "disk space" meter for iPods, iPhones and iPads has been subtly changed as well, removing the gloss highlighting and replacing it with a satin finish.
• The maximize, minimize, and close buttons are now arranged horizontally rather than vertically, which begs the question, will this change be rolled out within all Apple-made apps?
• A new social network named Ping is available which allows you to follow artists and other iTunes customers and share your musical interests.
