|Kate is by far the best *nix text editor out there ;)|
|enlighten me about good editors on other OSes|
I use gedit. It has a simple interface, a reasonable number of features built-in (including find-and-replace that allows escape characters, something that seems to be missing from a lot of editors), uses sane hotkeys (which Notepad "Ctrl+D duplicates the current line" ++ should learn from) and is easily extensible with Python plugins.
I did use Kate for a while and, as I remember, I knew I would have come to like it if I had spent the time to
|show me screenshots|
You'll have to find screenshots on Google because I only have access to Windows right now because I'm on my laptop after my desktop's PSU died yesterday. ResidentBiscuit mentioned the only graphical editor besides gedit that I've actually used (except for a gedit 2.x fork called pluma, but gedit 3.x is better).
There is also a cross-platform editor called jedit which is quite good, but for some reason I still don't like it.
You can actually get gedit on Windows, but it's an old version and it's also broken - the main one is that if you try to open multiple files from the shell, it will open them in individual processes, and if you try to open more files from the shell while it's running, they also get opened in individual processes. The only ways to get all your files loaded in one window are to drag them from the shell onto the window, or to open them one-by-one from within gedit. So, yeah, don't bother with it on Windows.
|There is a evaluation copy that has no time restraint, i'm not sure if they even specify that it can't be used for commercial use. Though it only costs $70 (was $50 or something before sublime text 3).|
Is the evaluation copy not crippleware? Also $70 is a lot to someone who currently can only spend about $50 per week after food, bills, rent, etc. Being a student is great, but I really, really need to get a job :P
