The important part is the _XX, not the -bYY. The bYY may be something
we don't care about, but the _XX part is something which may cause

We don't ship with java at all... strictly speaking. ;)

I fully agree. But number crunching (as benchmarked, and I'm not
talking about LAME which has a 2% difference) is not something almost
all users will do. Something the masses may do with the OS is not
covered at all, no browser tests, no interactivity (maybe with high
load in the background) tests. As I said, they don't even tell what
they want to test (and as such, everything we can do is speculate...
that's not something which will lead to interesting results in the
Man must shape his tools lest they shape him.
