We are often asked why dropbox over free onedrive?
Why should I pay for something I can get free?
One of the biggest reasons, besides what we see below, if that Dropbox’s primary product is Dropbox, and if this product fails, the whole company does.
On the other hand Microsoft, Google and others have a suite of products meaning that they are not reliant on one product, and therefore can “sometimes” not put the effort in. I am in no way saying this cant or wont change in the future
