Interesting article here titled Dolly Drive 1.2 expands to 2 TB. To give more perspective to those readers I added this comment:

This isn’t a comparison of that service, but it does have some good information. At these prices I don’t see that it will be popular. After all you can buy that kind of storage for a little more money, and it is too expensive for business as well. Perhaps it will do well if it has strong encryption or better security features than DropBox that recently had some security issues.
