This is confusing. Some things are accurate (yes, Linux sound output
is a mess), some things are hilariously inaccurate ("No analogue of GDI or GDI+"? Hello, standard X primitives and XRender! "fonts antialiasing settings cannot be applied on-the-fly"? How come I've been doing that in GNOME for years?) Also, "Both GTK and Qt are very unstable and often break backwards compatibility"? Even the latest versions of GTK+ are ABI compatible all the way back to 2.0.
So, uh, take this list with a grain of salt.
