Thanks Geraint. I'm having a look now on Amazon.
I usually only would buy another keyboard if there's something wrong with the one I have, but.. I just can't see it in the dark, so a fully lit keyboard is certainly an option. I think this one
is the one I have now but it's only got 4 keys illuminated. I was looking into it more in case there was some option to light up more keys but it doesn't look like it.
The only thing is I'm not sure if the Logitech one would accept simultaneous keystrokes, as you might use when gaming. I do pretty much all my writing on my laptop and mainly just use the desktop as a gaming machine (99% of the time). Maybe a full, backlit gaming keyboard might be the way to go though or something like that. I'll definitely look more into the options.
