Yep
When you go for an interview, and you're asked which IDE you like best, and you state: "I don't use any IDE, I'm a Unix guy", I'm going to bet you ten against fifty that you wont get the job (I would not hire you), the reason is this, all professional IDEs allow collaboration between developers (check out, check in, restore, etc...), collaboration is the name of the game, my strong suggestion is that you get an open-source IDE like Eclipse and a build tool like
ant and start building some projects from scratch.
Hope I was not too harsh, however, you asked...
