Here's a small fart to tackle (or perhaps just take back to the RND team
1 - Logitech G930's - can I STRONGLY request an suggest you make a headset on say the 5.8ghz range, 2.4 is crowded and both my 930's drop out continuously (this is the most common complaint I've seen and one I suffer from)
2 - G910 (which I am currently typing on) love it, feels awesome but, suggest you a) don't marker the 'WASD' keys 75 million League of Legends players don't use them as primary keys b) put a screen on a model, arx control while seemingly good is currently so sandbox that stepping away from a G510 like my other keyboard feels like a step backwards c) for the current model put the ability to charge the screen device and let fly with landscape mode.
3 - The next top end series (680, z5500, 906 successor) should really hate dolby atmos support (only reason I haven't upgraded my 5500's is it's not a step forward at the moment)
4 - any chance of seeing a g700 ilk mouse with less buttons on it (great mouse, fantastic wireless, weight, feel, just not everyone has a use for the extra buttons on it)
5 - Lastly LGS, good software, but you might want to tell the rnd team to sniff out what others are doing as well (like the lighting option in the sandbox for the g910, no option to switch/make colour maps easily, and well other makes have demonstrated a borderline language in the lighting control - someone has snake running on a competitor's keyboard) arx control is conceptually good, but at present I find a use for it.
I know I'm a demanding ranter, but I have 2 G15 series keyabords, a G510, a G910, 2 sets of G35's, had 2 sets on G930s, 2 G700's, Z5500, Z640, a myriad of older mice and keyboards and ALWAYS put logitech kb/mouse on any pc I build for anyone so I've had a decent hands on with a your products.
Keep making stuff, it's always fun to see what's coming out.
