Did you read my post, MichaelMroczka?
RadialMenu appears to be an elegant solution to other problems, but there's basic functionality missing from the Surface Pro 3 that RadialMenu doesn't seem able to provide, and that's the ability to use the barrel buttons while 'hovering'.
From a regular Wacom user's point of view, this means there's still no proper right-click or middle-click on the Surface Pro 3's primary pointing device. Some might be able to live with it, but do you think people would accept a mouse that worked that way? It renders countless apps & games unusable, unless you add... say... a three-button mouse, or a Wacom tablet. Do we want mobile/tablet PCs that can only successfully run a handful of apps, or that require a bag of peripherals?
This remains an open & unsolved problem, and apparently it's exclusively Microsoft's problem to fix. They maintain the driver for the pen (the hardware vendor N-trig doesn't seem to be in a position to help), and it's their fault that the driver doesn't pass right-click or middle-click through to applications like RadialMenu unless you also left-click at the same time. Microsoft clearly don't understand pens yet; everything they touch that's pen-related gets broken and left that way indefinitely.
FertileOctopus: if the lack of Wacom-style left/middle hover-click is a deal-breaker, you might as well return it to the shop, rather than waiting for a fix from Microsoft. I replaced my SP3 with a competitor's model using a Wacom digitiser, and I'm much happier with the replacement.
