i was certainly somewhat intimidated by having to redo configurations: early in my freshman year i spent the time constructing a reasonable

i actively enjoy learning and using ion. so far (< 24 hours). it does things the way i have longed to. no overlapping windows. frames and full screens. easy keyboard manipulation of the 'windowed' environment.
it is not eyecandy. it is a graphical usable interface.
