Right, there seems to be more color options in the small keyboard realm (notice the popularity of colored aftermarket cases for 60%ers), including white. However, there are very few white keyboards in full 104 ANSI or 105 ISO format. And mostly this is due to fashion. Black keyboards are the current trend.
You guys should look at keyboard covers. They keep the dust and crap out of the keyboards when not in use; and trust me it accumulates fast. I have one by "CDS" Computer Dust Solutions and it covers a full size keyboard or a 60% and the mouse. I imagine if you have a white keyboard this is more important for aesthetics, but for any board this is important. And every few days I wipe the surfaces with a weak Windex and a microfiber cloth.
Very white keyboards, such as the white POK3R look almost blue-ish. I much prefer a slighty off white, anywhere from the HHKB slight grey colour to the OG Cherry beige tones.
On that note, has anyone ever died a plastic case? I'm looking to turn my very white plastic 60% case into more of an off white:MoreShow Image(http://i.imgur.com/8OSetZv.jpg)
