Had to replace my laptop, and "upgrade" to 11 when I did, a little more than a year ago. Tried to reinstall my old MS Office suite and it wouldn't allow it. Basically, they've gone full retard on the whole subscription model. I was using it as an independent consultant, so I get to expense it, but it's still bullshit. And 11 isn't any kind of upgrade - it just runs more bullshit in the background, eating up capacity, and adds steps to do things I use to be able to do with a single right click. Also seems less stable than the "8" I used for years and the "10" I had on a client's machine for a while. Software folks used to be pretty smart; now it seems to be bunch of trained monkeys doing their level best to NOT put an efficient, effective and reliable product on the market. It's the whole "engineered obsolescence" bullshit. I wouldn't be the least bit surprised if updates weren't designed to degrade performance, whether phone or other device, starting as early as the 6 month mark.
