As noted by others I was using the previous trend with ME devices in leaving the "s60 button cluster" silver. However, this weekend I'll try to do up a version with black, as well. Also, if anyone knows Photoshop better, feel free to either steal that image or email me for the original if you're bored and want to clean it up a bit. I've used Photoshop a grand total of 3 times now.
I've always wanted an S60 device with user-changable keypad backlights, like a menu setting or something. Not that hard, toss some multi-colored LEDs in there and use clear film for the keypad. That'd be AWESOME to be able to match my keypad backlights to my theme.
