A must have upgrade for many
For all its crap* and bugs, there are compelling reasons to upgrade from Windows 7 to Windows 10:
- launch speed
- DirectX 12
- Additional hardware support
- screen scaling for high definition screens. First test show it finally allows per screen configuration - or at least per graphic card, need to test on more hardware.
- better audio chain for pro audio software, let's hope they'll take advantage of it.
- better security (admittedly)
- and more
Some will want to keep Windows 7, but frankly there are less and less reasons to do so.
Also to be fair to Cortana, a personal assistant must be personal. If you don't want to give access to personal information, don't. Yes, privacy options are spread a little too much, but at least they exist and are not fake (hello fb).
* My personal pet peeve is the fact that closing a windows in tablet mode forcibly brings back to the start screen or whatever it is called nowadays. This is wrong on so many levels. You are browsing and a windows popups. You close it. No, you don't go back to the browser. you go back to the start screen.
