is it? the new natural keyboard is literal landfill, the surfaces are great until they break, i don't think even MS can open them up for repair without destroying the damn things. The surface studio was apparently a technical dud and way too expensive to boot.
The xbox 360 had such terrible heat dissipation problems that it got it's own moniker 'the red ring of death'.
In the old days their HID device devision was solid, and was doing some interesting things. Back in the 90s-00s their keyboards and mice were pretty much best in class (if you wanted a membrane keyboard), the natural keyboard was a big step forward in ergonomics. On the gaming side they had solid mid range flight sticks that the rest of the industry lacked (it was either crazy high end or literal trash). Hell they even tried some coolish experimental devices that were at least interesting .. Specifically I'm thinking of the Sidewinder Strategic Commander. A kind of one handed keyboard that was sitting on top of a two axis sliding mechanism.
In the 2010s they did some interesting devices (or branded some) like the kinect and the original surface tables (the ones that looked like cocktail style arcade machines)... and they started moving into compute devices like the 'second gen' surface branded tablets/convertables/laptops. Those seem less successful overall. I don't see too many enterprises giving people surfacebooks instead of lenovos...
I don't know which generation of natural keyboard you mean, but the one I have is wonderful, and my two generations of Surface Books have been absolutely beautiful devices - yes they've got soldered memory and can't really be repaired or upgraded, but that's par for the course for a tablet (and increasingly for laptops too - I think most MacBooks are like that?). I honestly don't know why they're not more popular with corporates other than Lenovo/Dell already being established there - they make great development machines and are wonderful in a "fixed desk with a docking station but also use on the move" scenario.
MS have definitely had some failures and weirdnesses (and a few straight up "should never have happened" issues like the RROD), but that's part of innovation.
