So the title pretty much says it all - I consider Cooler Master Inferno to be one of the best mice even by today's standards.
Sure it might be a little dated with a 4000DPI sensor and lack of proper RGB, but it has something that no other mouse in the world has - excellent symmetrical placement of 11 buttons combined with support for a lot of customization thanks to the "Storm Tactics Multiplier key" and easily accessible profile switch button (can't believe I'm marketing a CM mouse back to CM :P). This makes the mouse into a multimedia powerhouse without the need to place more than 3 buttons under the thumb.
I'd love to see an updated version of Inferno hit the market one day. My couple of ideas:
Leave the button placement as is. The way each button on top has a counterpart (symmetry) creates some good mapping opportunities. For example I have set up Storm Tactics (let's call it ST for short) + left click to be browser tab to the left, ST + right click is browser tab to the right ST + right quick fire key is close tab while ST + left quick fire key is restore recently closed tab. On another profile I have multimedia control set up - ST + left quick fire - volume down, ST + right quick fire - volume up, ST + MMB - mute sound and right quick fire is just space (for stopping and starting playback).
For even more functionality the scroll button could also click to the left and right - that's two extra buttons without changing the overall mouse layout,
Obviously update the sensor (don't get me wrong, it's a very good sensor but 4000DPI might not be enough for some people and some high resolution displays nowadays),
Add proper RGB this time around,
I would like to see support for more than just 3 profiles and a couple of scripts,
I don't know how good the PC software for your newest mice is, but the one for Inferno while usable has some weird quirks and is overly complicated and unintuitive - it might discourage some people.
Leave the DPI setting indicator - I love it!
Add replacable weights for even more customization!
I wanted to write to you (CM) about this for a long time actually - I'm still using an Inferno that I bought 7 years ago (it's my second one actually) and I'm afraid that when it breaks I'll lose a lot of functionality because Infernos are impossible to find anymore and no other mouse has what it has. And also having an updated version with even better functionality would be a godsend.
