You have a point but most people I know use a computer for years, until it is about dead due to age, and the hard drive isn't even half full. I have a neighbor that bought a computer several years ago with a 1TB drive. Last I looked, it had less than 200GBs of data on it, including the OS. Sad to say but when a drive fills up, most people would think the system is broken and just go buy a new one, while losing the data at the same time. Most people I know, don't even think about transferring data from their old system to their new system. They just assume a video or whatever won't work except on that old system so they lose everything. It's sad to say, even about some of my friends and even family members, most are clueless about how a computer works and how easy it can be to transfer data from one system to another. Same can be said with backups. Especially if you don't have a lot, online backup services can be very easy and require nothing from the user. Dale :-) :-)
