Value is, admittedly, subjective. I once felt the same (this much for storage!?) but let us enumerate the value: 2TB of durable storage with highly reliable syncing services, web interface, mobile apps, selective sync, sharing/links, etc. Is that enough to make 10€ palatable? To each their own value decision. For me, the time savings using the product and the piece of mind are worth the cost (although I also pay Apple $10/month for iCloud storage, and would move from Dropbox is iCloud files reached parity wrt sync/selective sync).
