As bad as it sounds, disruptive technology isn't that bad at all. Well, not from a consumer's perspective, that is. They are innovations that create a new market/competition by using a current technology and applying different sets of features and values.
My favourite and the one I use almost everyday is my digital SLR camera. Around a decade ago, very few people were able to purchase digital cameras. This is because film photography was still used vastly. Nowadays, almost everybody has a digital camera. The reason why this technology was so disruptive is because quality was no longer an issue with digital cameras. Also the convenience of memory cards gives a chance to take thousands and thousands of photos. Not having to develop photographs is also a main reason as to why digital cameras are convenient. As of today, most cellphones are equipped with cameras as well. Later on in the future, digital cameras might be out of the picture as there might not be a need for them since cellphone camera quality is getting better and better.
Sustainable technology has the capacity to endure. One sustainable technology I use very frequently is water. Water is recyclable, and there isn't really a substitute for water (for now, at least).
