I don't even use it on a weekly basis, uses it once in a while to jot down notes, or paste links I might want at a later stage, so I do not cost much money. I have it at work, home + my iPhone. Doing a 2 device limitation might push me to OneNote. Or I might use web interface only. But cutting down the service for existing customers (even freeriders) is the way to get enemies, not happy customers. Box.net gave me 50GB for life when I was an early user. They keep that promise. So they are always in the back of my mind as an alternative to DropBox.
