Those are good points. My current drive is 64GB (with 10GB dedicated to TTP's eDrive). That is rounded off from the 80GB advertised size, and at 64GB the old drive is not quite up to the doubling of space required that I have seen in the "literature". Thus, I suppose I would need the entire drive, perhaps and then some. I'm probably better off buying at least a 150GB drive, or whatever size is just higher than that. Before that realization, I was already giving consideration to your second point. Thanks for your input.
