Thanks for that. I've picked up a Logitech G915 with the clicky keys. A couple of comments, it's 'ok', feels very cheap considering what they cost, rattles a lot. Typing is ok on it, better than with those linear keys, but still feels poor quality. Not a big fan of the low profile design.
The Asus I have is built like a tank, no rattles, feels solid, has a nice feel, but those linear switches I just can't get on with. They do make one with more clicky switches apparently but after a couple of months of trying to find anyone that had them in stock gave up and got this version. There is also the issue that f5-f12 default to being media keys until manually switched with a hot key combination. Not that I'm too fussy on the software to program the keyboard, but whoever Asus got to write their software is an insane lunatic, how hard could it be to be able to assign colours to individual key and then write that to the keyboard? It's only possible to assign a single static colour to the entire keyboard. In comparison the Logitech software is not much better, it's like they gave the insane person who wrote the Asus software different medication and let them at it.
If someone made a keyboard like the Filco but had a wireless usb dongle for connectivity and some backlighting that would be near perfect.
Thanks for your help.
