I think I'm about set to go with the non-backlit Pok3r. Although some conflicting pictures, most seem to indicate that the backlit version won't have the Fn layer legends on the sides of the keys. This would be my first 60% board, so I'm pretty sure I'll need that to get used to things. For me, the backlighting was just an occasional thing in a dim lit room, and mostly I envisioned using it as a reference to the Fn layer. So overall I think it would be relatively useless for me.
Now to just decide white vs black. Normally I'd go with black to match pretty much everything else, but the Pok3r black keys seem a bit more charcoal, and the white looks pretty nice. Other than initial looks, is there any problems with white yellowing over time on these boards? Or pretty much a non-issue these days?
