While the disk difference is a bit unsettling, it probably isn't a showstopper for most people. I was particularly concerned with volume of data over the net, because if too large it would be a showstopper for those with dial-up connections.
Like others have pointed out, SVN caches the latest update locally, which makes diffing your local changes very easy. That's why it's almost exactly twice the size of CVS. I think it's a reasonably small price to pay, not to mention a good tradeoff to reduce network bandwidth, since disk capacity is almost always cheaper than bandwidth. In fact, local caching is necessary to achieve the 2-way diff, which is really the major win. The fact that you get a fast local history is just a nice side effect that I think indicates an elegant design. Dave
