Okay another Idea, why not add a downwards compatible Blu-Ray Burner to it! Sure it wont fit in the Mouse, but Mousepads could handle that part!
While we already talk about accessories, the Mousepad could also do Wireless Charging for the Mouse, as well as handling all the Thunderbolt-3 Stuff wirelessly!
Floppy Disks are such an antiquated thing, but people in Japan still use it and we ofcourse dont want to ignore the Market for that! So a compact Floppy Drive next to the Blu-Ray Burner inside the Mousepad!
The Mousepad should ofcourse have a combined Audio Jack IN/OUT Port on both the left and the right! Yes there is Audio Jacks that can handle Microphone and Stereo at the same time without needing 2 cables! And if you really need to have separate Audio-IN/OUT, you can always just use an Adapter Cable for that, I have one of those, and money clearly isn’t a factor for this Luxurious thingamabob!
The Mousepad should ofcourse serve as a USB 3 A and Thunderbolt-3 Hub. The goal of this whole Setup is that you can plug everything through the Mousepad into just one Port of your Computer, including the Monitor, and Thunderbolt-3 can ofcourse handle that too.
Now having a huge Hub on that Mousepad might consume a lot of power, so lets add a Qualcomm Quick Charge Port to the thing and also a separate Power Input you can plug into your Wall. That way you can just plug your Phones and your Pads into this thing at all times for recharging!
Adding 2 Ethernet Ports to this thing is also a good Idea, so you can plug in your Internet at the Mousepad, because obviously your Computer has nothing but a Dual-Thunderbolt-3 Port to connect to, and one of the two is already used for Power Input. And yes such a Computer already exists! Why else would I talk about this abomination of awesomeness!
So here we go, the perfect Mousepad for the perfect Mouse!
The Ultimate Dongle!
