Depends on how you configure it, it can be a lot of things. The UI is pretty amazing, but I don't have the knowledge or time to do it justice in the least, sorry :)
To be perfectly honest, the first time I finally tried it after hearing so much about it for so long, Sublime Text kind of disappointed me. You can't even print out of the box -- waitwhat? It does other cool things, true, and there is room for more than one text editor, text files are awesome that way. But still, I felt a bit like when everybody was going nuts over Firefox because they didn't know about Opera. I love Mozilla (a lot) and harbour no ill will towards Sublime Text, but god damnit, software isn't as tight as it used to be. I don't know anything about anything and even I can tell.
Printing isn't a task for a text editor. If you want to print something, open it in your word processor. I would be disappointed if the Sublime devs wasted a bunch of time developing 3-platform printing support when there are about a million more useful editing features they could be working on instead.
How is it to use?
