Hey, it's served us well over the years.

A fun thing to do with new technologies that claim to replace old ones is to
imagine that the new one had been invented first and the old one was the 
replacement.  Would you be able to sell the old technology on the basis of 
its advantages (at least to some people) over the new?

For example, I think you can make a case for VHS (or even better in theory, 
Betamax) video tapes as a user-friendly replacement for DVD.  Instant record
function with easy incremental updates and relatively good reliability; smooth 
linear search function with a continuous visual update; remembers its 
playback position between uses; larger capacity; more robust (the tapes 
degrade more gracefully and are much harder for a toddler to destroy 
completely).  Downsides: bulky to store, picture and sound quality not as 
good, omits some (generally worthless) extra-features crud, although also 
some potentially essential things like captioning, harder to seek to 
predefined positions.  Sounds like a reasonable tradeoff.  I know which one I 
prefer to use day to day, and it's not DVD.

(An inclination that got us into trouble recently when we went on holiday to a 
rented cottage taking several kids videos with us, only to find they only had 
a DVD player.  I'd forgotten video was supposed to be obsolete.)

Similarly, I could probably sell you FM as a significant improvement on 
digital radio.  I'd struggle with LP records... I suppose I could try 
pointing out how much more crappy unwanted filler material you get on CDs 
that there wouldn't be room for on this nice low-capacity format.  Probably 
couldn't make much of a case for CDs over your shiny iPod either, but that 
has more to do with their being too different to be easily susceptible to 
that sort of comparison.

Anyway, this is all a wholly pointless digression, because what I was thinking 
was just that you can't make a case for CVS over Subversion.  I can think of 
two advantages it has: working copies are half the size (Subversion stores a 
whole load of stuff in the .svn directories, which is handy because it means 
it can do diffs and status reports without querying the repository), and the 
repository is a bit easier to study directly if you need to.  Not enough.

Of course, I know where I've read this sort of thing before -- the Emacs 
reverse changelog, in which they try to re-cast all of the fixed bugs and new 
features as more interesting behaviour and slimmer code in the older version.  
What did they actually call that file?  A quick search doesn't reveal it.

Yep, looks like that worked.
