If all you need is a GUI application that lets you type text, then you aren't serious about manipulating text.
Ah, the Slackware/Gentoo argument. Yes... I remember these:
h4x0r: slackware/gentoo r0x0rs - RedHate is for n00bs
h4x0r: because it's not 1337
h4x0r: because serious h4x0rs use slackware/gentoo
me: what can they do with it that I can't do with RedHat
me: spending 3 hours of tedious (yet straightforward) time installing
+doesn't make something useful.
h4x0r: serious h4x0rs use slackware/gentoo
me: go away
Same deal. As for "serious text editing" I use Perl, hit up cpan, write the scripts as reuseable components, and laugh at everyone else like so: ha haha ha.
