I just got my Filco Yellow-key TKL for Christmas. I had all the Filco's I don't own on my Amazon wishlist, and my sister picked this one out for me. She deserves hugs. Possibly drugs.
I think you've all convinced me I really don't want a USB port on the board itself. I definitely agree if it would take away from the "clean look" of Filco at all.
Those that want media keys on their Filco - have you seen the Camo version? It has media function keys, and is the reason it was my first "nice" keyboard I bought. It is of course, in a camo pattern, so bringing it in to work may get you ridiculed a little bit
I ended up really never using them though, so I forget they exist most of the time. Simply not a feature I look for anymore.
Detachable USB cables aren't high on my list, but I wouldn't complain either. The best USB cord on a Filco I've seen is again on the camo version - it's a heavy plastic braid type. I just think the connector is yet another wear point that will eventually in time break and need fixing. Lord knows most phones I've had died due to the USB charge port being the first thing to go.
So.. I'm going to simply go with...
A bit better Q/C - I have some boards that the key holes (especially noticeable around the arrows) are misaligned. Rather annoying on a $150 keyboard. That, and if they would - some thick PBT keys of some sort (even as an option) so I don't have to hunt high and low for a good looking set that will match the board well.
I also still think a Filco TKL that looks as-is, but has well done backlighting (e.g. apple does this pretty well) would be great. I also don't think it will ever happen.
Any suggestions for a good set of thick PBT keys for Filco? I know a lot of sets out there (from older boards) don't fit quite right. I do know whenever I watch Delta check me in, I want to grab one of their cherry boards and start running... Those caps look legit!
