Quick Win
If they're looking for a quick sale they should re-release the "Microsoft Natural Wireless Ergonomic Desktop 7000" kit, I'd buy several so I'm stocked up for the future.
The one I'm using to type this on is missing the lettering on most used keys (yes: ctrl x c & v, along with the nearby shift) and the faux leather's torn on the left side too (duct tape, is there nothing it can't fix) but the wonderous mouse that came with it has long since died and literally nothing else on the market fits like it did, was beautiful, the MX Ergo I've settled on, although great at preventing anyone else from using my computer, still is a poor substitute.
The same keyboard I have at home is fairing better, but they're increasingly harder to come by at a reasonable price (in a UK layout no less - I've gotten used to a lot of things since emigrating, but having the " and @ symbols in the wrong place is a step too far for this expat!).
And no, I'm not prepared to pay the $600+ AUD for those still going on eBay (which, bit hint Logitech, you have a product there's a demand for unlike the toy like tiny new replacements that do fuck all to help the RSI they're supposed to resolve because they're too fucking small!).
If microsoft don't want to be involved because they're not new and sexy anymore, just give them another name and badge, but please re-release them!
