Why not? Are you good at math? Did you know that average internet connection in US is 12mb? It will take days to sync 256gb of files from the internet wirelessly. And what if you don't have wifi and rely on your cellular connection that limits you to 2gb of data per month? Then you can just forget about cloud stuff at all.
What math? The key here is average. You know it's average. Someone who might benefit from that will probably have higher than average.
