With the quality of the Macbook camera, you could even use a draw of the user and the system will log in lol I think Windows Hello only works with certain kind of web-cam.
It uses an infrared sensor-type camera. It prevents you from just holding up a picture of a face (already tried). It's extremely accurate and works well. I have a surfacebook pro 4 for work, and I have to admit, very nifty feature..
Windows 10 is simply a tolerable version of Windows 8 which was terrible.
That's definitely a matter of opinion. I think Windows 10 is leaps and bounds better than windows 7 and 8 for that matter. Everyone I work with agrees and many (if not most) reviewers also agree Windows 10 is a huge step forward. You need to look beyond just the start menu change.
I can agree that maximizing is more consistent in Windows. In OS X double-clicking on the title bar (or alt/option-clicking the + button, depending on how things are set up) does zoom the window to the entire screen most of the time in most apps, but not always. Sometimes it ”zooms to fit” like in Safari and Finder. This doesn't always work consistently depending on what is viewed within the window, so I think I agree Windows handles this a bit better. That being said, I rarely see the need to zoom a window to fit the entire screen. For most Windows users, this is often first thing they do when they open up an app – double click to mazimize. Why? There's most often not a point in running a web browser maximised on a widescreen display you will just get blank sides with no content.
Not to mention how awesome Windows snap is. I have to admit, I love my mac, everything about it. But windows snap is such a useful feature it drives me nuts that Apple doesn't do something like that. I know they do split on fullscreen, but it takes on average 10 seconds to do so and way too many steps–make window fullscreen, wait for animation; swipe for mission control, drag another window to the new fullscreen window. Wait until the animation finishes. Swipe to go to the new space. With windows, it's drag title bar to side, click next window, done. Less than 2 seconds. You can also resize one window and the other resizes it–I know mac snap windows do the same. Unsnap the window and it takes back it's original size.
I know there are thirdparty components to do that on a mac, but they are unfinished. You can't resize windows after they are snapped and have the other half resize with it.
Definitely A+ for that in Win10 for sure. Well designed and works extremely well.
