I'm not sure if it is in fact the Model X, but I just received a warning from my ISP that I have used 75% of my capped bandwidth (750GB/month) for the month of March which is only half way done. Looking at the input/output stats for the past two months, beginning the week after I took delivery on Feb 3rd of my X, the data usage went from about a combined 5GB or less a day to over 30GB and as much as 40GB combined a day. With download and upload amounts about equal. Maybe it is a coincidence but daily usage began to climb the day I took home my X and I don't know of any other changes in Internet usage in my house around the same time. Has anyone else seen an increase in Internet usage since getting their X or S? I've turned off the wifi in the X to see if it makes a difference.
