Good enough reason for me.
I loved CDs when they came out because they were so much more convenient than records. I loved DVDs because they were more convenient due to the fact that they held more data than CDs (I'm talking music...the digital improvements over consumer-grade magnetic tape for video and audio were amazing, too, IMO). Hard drives...even more. With digital data, it's all about storage. I'm guessing that in less than 20 years, we'll see something that most of us haven't even considered.
