WTF???
WHITE CLICKY NMB? Seriously these guys are having a laugh. They changed their colours more frequently than their underpants. (Clicky is supposed to be black, and white is supposed to be linear. Linear white is normally one-eye, and I don't know for certain that the two-eye whites I saw were linear.)
Clicky NMB has a very good reputation. For the record, can we have a photo of the rear label for cataloguing purposes? Also, what colour are the space bar and caps/num/scroll lock switches? Those four are often a different colour, and the space bar switch should have a spring twice as long inside.
The Dell with black Alps — hard to say, it's a bit of a love/hate switch, that.
