The loss of which I've bemoaned for about 30+ years. This, or something very like, it is exactly what I want going forward. My biggest concern would the fate of my virtual computer should the provider go belly up. Without providing for that contingency I'd be really hesitant to put all my eggs in the basket.
I'm awfully leery of giving someone else total control over my computer for any reason. Take the security concerns over Dropbox and cloud storage and multiply them by 10. Convenience is great, but I'm not sure it's worth the prospect of willingly handing someone else complete observation and control over my entire computer and everything I do with it.
