I agree that it's a bit late but I don't think the issue is use of Windows (or Word, if that's what you're implying).

> It's an awesome replacement for MathType. It uses OLE so that it embeds in Microsoft Word nicely.

But that's the rub - OLE doesn't embed particularly nicely. I haven't used it in over a decade (maybe two?). It's sort of very softly deprecated.

The new equation editor in Word which isn't based on MathType, and doesn't use OLE, works much more smoothly than the old one, even if it doesn't support everything. ("New"? I just checked and it was introduced in 2007!) I think a typical user would have to be really desperate for extra functionality to abandon that level of integration, at which point you'd probably switch away from Word altogether.
