Swipe gestures are a pain with a mouse, because you need to move the mouse to the right spot, click, drag in the opposite direction and then release, requiring a non-trivial amount of effort; and it just feels wrong when you're expected to do so regularly because you know there has to be a better way (like the way it used to work). Decades of desktop UI design focused on "discoverability" also mean that an unindicated need for a swipe gesture in order to access core functionality is frustratingly non-obvious to people experienced with classic desktop interfaces, and these will tend to be people whose advice is requested in purchasing decisions.

Swiping is awesomely natural on a touchscreen, but obviously sub-optimal otherwise. Reliance on a swipe gesture should be avoided in UI design for a mouse/touchpad and keyboard environment, in favor of buttons and menus, and mouse wheel/two-fingered scroll support.

If swipe gestures even work with the mouse in Windows 8, I didn't know it and it never occurred to me to even try, though now I'm curious to see what happens when I get back on my laptop. I never even considered trying. You don't do swipes if you have a keyboard and mouse in Windows 8, you use your buttons, menus, clicks, and mouse-wheel just as you suggest. Where did you get the idea that the Win8 interface required gestures?

You don't need to swipe, you just move the mouse to the corner of the screen (or use the keyboard shortcut.)

So you can! Well that's embarrassing. Guess I could try using the thing before I stick my foot in my mouth.
