Yep, its white. As white as my old iMac.
The web cam and the mics work perfectly. I didnt have to do anything. The MBP just uses them automatically when I use it in clamshell mode.
I know what you mean about "white as my old iMac", I just wish the original keyboard stayed as white, hopefully the Dell won't yellow with age. Glad to hear that the web cam and mics work. I'm not real keen on the white back, but it does seem like a really nice monitor otherwise.
