ICT in ESL teaching

So, I got thinking today... "how important is the use of ICT in ESL teaching? Having never my own classroom computer and still use a chalkboard, such luxuries have never been available to me. Granted, I've got all the ICT resources provided by the editorials, but they have hardly ever been used. I started to wonder if my students would have made more progress had they the opportunity to such media? I use my laptop every single day of my life and make my own resources and flashcards from it so I often ofter could language learning and acquisition be reinforced through this media? I would love to know if anyone has idea regarding what kind of activities are available and productive?
