I think it is needed. Tell us all about how your teeth clench when all those tiles and goofball things come up and so forth...
Ok then... I hate those tiles so much I have the opening screen set to look like Classic Win 7 so I DON'T see those irritating tiles.
My first experience with a computer was learning a bit of BASIC way back in the stone age on a then-revolutionary and brand new Commodore Pet computer. (I think it was a PET). The first one I owned was an Epson QX-10, CPM based computer, way ahead of DOS at the time. Second one, for writing and editing music (still 5 1/4" floppies with an amber screen) was a custom built DOS with Win 3.1 as a program to run, computer that played the call to the races (da-da-da-DA-da-DA) when I turned it on and couldn't silence it. I opened it up and disconnected the speaker, listened to the music stuff on headphones.
Then a series of good Toshiba machines, and most recently Lenovo business machines.
Not one of these had or has tiles that blink or move, and neither does my tablet.
To me, those blinking tiles, though I know others like them, make me feel like my machines and the people making them are treating me like I am an idiot who can't operate my own devices. I find them very distracting and irritating. And I am trying to figure out how to disable Cortana in Win 10 without hurting any necessary operations, haven't explored that in detail yet.
But that's just me with my history with computers... all changes are not necessarily good ones.
'Nuff said?
