General W10 observations and things I like:
1) Cleartype definitely better - HUGE WIN HERE.
2) Seems like read/write to the SSD is faster. For instance when I compact my Access database it seems quicker.
3) Headed in right direction on Start Menu although has a ways to go. Make it transparent. Allow me to drag apps from list on left to tiles. Allow me to turn off animations. Make click and dragging tiles less twitchy. Allow me to select multiple tiles. Allow me to edit tile text. Provide templates that will autogroup tiles by app type (nice starting spot). Give me a bigger button for viewing all apps - that thing is tiny and I often have to click it multiple times for it to work (actually just hovering over it to activate would be nice).
4) Really like the borderless windows with shadow effect. Classy which means MS will probably ditch it (hehe).
5) Tiles are cool but boring. Instead of have just a little app icon in the middle of a big tile, have the icon fill the whole tile bleeding off the edges as in Android icons. Add a little sweepaway animation to tiles when I click one as on Windows Phone (always thought that was cool).
6) System feels quick overall but not really noticeably quicker than 8.1.
7) Like the clean overall look and feel. Window animations could be more interesting. Zoom in or something, or at least options for that.
8) Love the multidesk and window snapping. Super cool and handy.
9) Add
jump lists to Start Tiles. This would be HUGE. Maybe activate them just by hovering over a tile since right click is already being used. If my Start Tiles had jump lists I'd barely even use the Taskbar.
10) Although HD Control Center has been excluded the built-in gamma settings found in Display work quite well and look great dialed all the way down.
11) IE is a mess. Same with Chrome. Surprisingly Firefox is the most stable (and fan free).
12) The new windows have a burger button at top left with options but I think they should also add just one button which activates the pop up options for the app. Average non tech users will be confused by the double step to get those.
The biggest problem M$ has is that they think like engineers. This stuff all seems intuitive to them because they wrote it, but to the average Joe seeing it for the first time, it's not intuitive at all. Here's a basic rule of thumb. If anything takes more than one step to accomplish you will immediately lose 1/2 your audience. Make it OBVIOUS. Why do you think people love Apple? Because any idiot can make it work.
P.S., I'm obviously goofing off and not working today which is why I have time to write stuff like this. I've been an IT Consulting Headhunter for 30 years and sometimes by Friday I get sick of the sound of my own voice on the phone.
