Onmidrive

From the Seomoz.org Web 2.0 list of awards I chose Onmidrive in the Digital Storage category. Digital storage is nice for documents you might need when away from your computer. I don't know if I would trust having this service for all my documents, however. What happens if the company shuts down? Are all documents lost? It seems too risky for me. Also, the storage amounts are too small for use of anything except temporary storage of files. The free account only gives you 1 gb of storage. The pro3 account, at $200 per year, only gives you 50 gb of storage. I'm not impressed. Nor would I use it in a library setting.
