edbro, I don't think Quicken will ever do that, or need to, unless some market research shows there's money to be made, much like Adobe won't write (or port) a version of Photoshop. Just not enough users to justify the ROI. For myself, I'd kill for AutoHotkey (not the weak substitutes); UltraEdit damnit!; NewsLeecher; and XYplorer. I'll eventually get around to testing a few apps under WINE or their Linux versions. I know that Opera works just the same as under Windows, and the same skins are used, so I was able to make it look exactly like it is in Vista.
But the reality is that under GNU/Linux, either the (free) software is different (cf. KM/GMPlayer and VLC vs. GomPlayer for me), or the Windows version is mature, as in commercial software. This is the same reason I often laugh at the mac folks. When I look at software on my friends' macs, yea, it's all polished, but most of the apps seem unfinished or they make you work in very different ways. I think someone else mentioned in another thread that the one great contribution of Windows in the early 90s (and then especially with Win95) is UI consistency. GNU/Linux doesn't have that because you can not only choose among half a dozen different desktop environments, but you can customize each far more than I ever dreamed in Windows. Great if you got time to futz around with it; however, I don't.
