I'm less worried about reliability and more worried about having easy access to my stuff when on the road. With 10 computers, I inevitably have copies of my important data distributed everywhere -- it would just be nice to have a cheap canonical source I can pull from occasionally. I'd also be okay with paying a large upfront cost (say $500) to buy hard drives and then paying small monthly fees for bandwidth/electricity/support. It doesn't seem to be too hard to make a profit doing something like this. The last solution I can see is to make upfront and ongoing fees cheap but make me pay through the nose for downloads. I'd be willing to pay $50 per gig to download if it were free to upload/store. (I have really low usage requirements asides from storage.) So I feel an entrepreneurial company would be able to make a profit in this realm (correct me if I'm mistaken) -- I'm just not sure where one is.
