For me, the backlighting isn't so that you look at the keys while you're typing, it's so that you don't start typing with your fingers shifted to the side and have to back up.

That's what the "finger alignment ridges" on the F and J keys are for. They were there long before keyboards were backlighted. (Or are "modern" keyboards lacking those ridges now? I don't know, the newest keyboard I have is 12 years old.)
They're on my Microsoft Sculpt and the 8 year old Thinkpad in front of me, so I don't think they've disappeared. I guess I don't notice them when I start typing? I'll have to try and pay some attention to them.
