A linux distro with all popular apps rewritten from scratch to use a single UI toolkit and consistent default keymaps, for a smoother desktop experience.

It's one of the reasons I have a tough time switching full-time because all the apps I need use so many different toolkits/versions/random keymap variations (inconsistent font-sizing, ctrl+tab vs ctrl+pgup, etc) that even the thought of switching makes my head spin.

Love the way GNOME's been going though (Except for their default keymaps. Ctrl+PgUp for Next Tab? Srsly?), and KDE is getting more consistent.

And yes, I know you can modify keymaps, but just wish they'd stick to widely used ones by default).
