Sure.  And if you have 3-5 developers there is no reason to not use CVS,
it works well enough.  Or Subversion after it matures, or Arch, or Aegis,
or tarballs+diff+patch.  

We can't, and won't, compete at that level.  You're comparing free against
what we charge.  We're infinitely expensive in that comparison.

OK, now let's look at it as you grow.  Most of our customers are in the 
25-100 developer range.  They move very quickly and have lots of parallelism
in the code.  So things like work flow and merging are critical, if that
doesn't work, the whole team slows down.  Let's say we have a 60 seat sale.
That's $90K/year for BK.  Let's say the engineers cost $100K/each (it
may be lower where you are but it's more like $180-220 here when you add
in building/mgmt/all the other overhead).  So that's $6M/year in engineers.
The BK cost is 1.5% of that.  You say that your guys are $50K/year?  OK,
so we're at 3% of that.  The point is that if BK makes your team 3% more
productive, it costs zero.

And none of that includes the hardware costs, which are dramatically
cheaper for BK, it works on a laptop.  Clearcase doesn't.

Whatever, I know that BK doesn't make sense for a 3 man shop.  And I
know you think it is way too expensive.  Your opinion is not universally
shared because the costs start to make more and more sense as you get
larger.  I am sorry if you don't agree but that's the way it is.  You
are welcome to use Perforce or CVS instead, we encourage it in fact.
