(Cloning this from the ransom thread)
Have any of you checked out Windows 10 yet? What do you think? As far as speed it seems really great but the look and feel is pretty damn nasty. They took away the ability to set the theme (I think that is the term du jour) to anything but fluffy and glitzy with terrible color choices. The default task bar color is black with (get his) black text and there really is no way to change that without making the entire UI look very harsh and unappealing. The main thing I do not like is the way they modified the start menu. There is no way to pin an app to the actual start menu itself other than to add those horrible bulky tiles. Then the 'all apps' section is sorted and differently and grouped by first letter. The simple clean list of apps and folders was MUCH easier to use. They really screwed up the entire start menu. A big miss.
The UI of Windows 10 kind of looks like a bad Mac clone. Not that this in and of itself is a bad thing, it just gives me that impression. They did of course give the entire UI an entirely flat look and feel. Which makes everything blend and run together. The title bar (I am not sure if that is the correct term) where the min/max, restore, and close buttons are had been redesigned and is (IMHO) much worse. First it takes up about three times the amount of space it did before. Then the close button is this terrible glaring burnt orange color.
If you are into bells and whistles you will love Windows 10. LOTS of those. I personally find most of them totally useless. Be aware, one of the things that is in the user agreement of Windows 10 is that you agree that MS can copy and save every document, image, media file, browsing history, web search, and location that you search form and do with it whatever they want at any time. You can turn most of that off but it is very cumbersome and you cannot (afaik) disable it completely.
Windows 10 is basically Windows 8.2+. It you loved Win8 you will adore Win10. If not, stay with your old OS.
