Check out the cross-platform LyX. It's an outstanding front end for working with TeX, on many platforms (Windows, Mac, Linux). I really enjoy using it. On many Linux distros you'll just need to install the lyx packages.

LyX gets you out of the presentation frame of mind, and straight into your content. Recent versions do a great job of integrating vector graphics (like SVG from Inkscape). PDF output looks fantastic.
