Cortana don't speak Aussie :-(
I can't even say I have a UK accent, it's region and language limited
Edge....a basic browser, scribbling on pages and reading mode is interesting but needs to be deeper to be of use. I use Diigo that has not quite as good scribbling, but the notes are searchable. Reading mode, Pocket has a good version of that but I personally end up reading the real version because I always think I've lost something.
It looks like they've changed the settings windows, again. It feels better but I'm sure I'll be trying to find the old interfaces again. I'm a power user.
It messed up my taskbar, but this actually got me to play and get happy.
I have a very intense taskbar. It's to the left and 5 icons wide. i.e I have a lot of apps quickly to hand. I have about 15 chrome profiles that I can start instantly via my taskbar.
W10 changed pixels around and messed my layout up. As I started to sort it out I realised that the new W10 had given me a new way.
The new start window is more of a popup. And the windows button shows it instantly. It has now become where a place my masses of apps. Make them small and what I call a lot is quite small, it fits without scrolling.
So, I'm currently positive this W10 will improve my productivity. Using the windows button gives me quick access to stuff I always use. And I get to see if it's raining while I'm there.
