Ah, too bad CVS doesn't have the concept of change sets. Imo, it's a 
reason alone to switch away from CVS.

Imo, it has huge advantages over CVS:

 * change sets -> accurate checkpointing to any version

 * integrity is verified
	* no difference between binary and ascii files -> data is 
	  preserved exactly no matter what

 * branching and merging
	* merging actually preserves change history instead of hiding it
	* merging is fast and easy

 * VERY helpful logging utility (try log --stat and log -p)

 * patch generation (git format-patch)
	* authors are preserved (committer is separate)
	* change log messages are preserved
	* binary diffs: all files are patchable
	* easy distributed development

 * all repositories are mergeable among each other (distributed development)

 * it's quote fast.. I've been using git at work, and it beats SVN
   in almost all operations
