That crazy Mik Kersten has provided two (1,2) nice articles about Mylar. If you haven’t used Mylar before, I would look over these articles to see if they can entice you to give Mylar a try. For me, Mylar is like a dirty mistress I hide from co-workers via two Eclipse instances and ALT+TAB. If you work with a lot of Eclipse projects and suffer from memory loss, Mylar is great 😉
By the way, Mylar will have a webinar in two weeks.
