Well that's almost gone for a while. Ever since they release Surface Laptop with pretty much no major innovation as to why get it compared to other well known laptop brands shown Surface becoming another Wimdows OEM. Though they eventually release Surface Duo, the cancelled announced Surface Neo and Surface Laptop Studio shows they can experiment, but it's clear that the first two is gutted. Surface Laptop Studio isn't as revolutionary as Surface Book either, but at least it also solves some limitations fro Surface Book design, even though I much prefer the former due to ability to be full tablet only when needed.
Surface Studio was nice as well, but due to high cost, it didn't shake the market and feels like refused to make cheaper version of it.
I always asked for a fairly affordable Surface Studio screen (~1500 bucks or so MAX) without the PC, so I could plug in anything I build, to be able to keep it upgraded, and have something with longevity with pen input and a nice high res screen. They missed out. Microsoft really needs to listen to its users.
Tech companies like to pat themselves on the back for their earth friendliness, but then put out products that quickly grow obsolete that are not repairable or upgradable (or if they are repairable, they want to charge you an arm and a leg for the parts / repair kit). This model needs to change. Especially in today's world. Batteries need to be easily removable, they need to be replaceable with a good supply chain. Screens too, keyboards, touchpads, etc.
Framework and Fairphone are the only two I think leaning this way. That will be the future, not thin-ness or marginal upgrades.
My Duo 1 battery on my second device purchased since the Duo came out didn't even make it through a year after I bought it in March of this year. Microsoft says, too bad, it's out of warranty, even though I bought it brand new in box this March from Amazon, so you can imagine how pissed I am about that. The Duo is far above other foldables in terms of multi-tasking.
Upgraded to a Samsung Galaxy S23 Ultra because at least I know Samsung supports their devices and stands behind them, not to mention they get a lot better press.
