This was not given as an argument for using align. It was an example that
just loading amsmath gives you benefits over standard latex.
The advantages of align are:
1. No extra spaces (eqnarray puts extra space before and after the middle
column)
2. Simpler to use
3. Works with the amsmath \tag command
4. Works with the amsthm \qedhere command

the alignmode makes only sense, if you have the same mathoperator
in all lines for the vertical alignment. otherwise it's a bad
layout. for example
\begin{align}
y_{12} & = a^2+x+d \\
y & \stackrel{\textrm{\scriptsize def}}{=} x^3+x^2
\end{align}
eqnarray centers the middle cell, so it looks okay!

this could not be the only argument for align ...
from my point of view, the user has a bad layout for the equation
when it's too long!

You can just use \stackrel{\makebox[0pt]{\textrm{\scriptsize def}}}{=}
and it will look OK with align. In fact, it will look better than an
eqnarray...

This was not given as an argument for using align. It was an example that
just loading amsmath gives you benefits over standard latex.
The advantages of align are:
1. No extra spaces (eqnarray puts extra space before and after the middle
column)
2. Simpler to use
3. Works with the amsmath \tag command
4. Works with the amsthm \qedhere command

Can we assume that anybody (or at least most people) have this ams stuff already installed when they use LaTeX or is this some kind of extra package left out of major distributions?

This is intentional: LyX now uses the align env. instead of eqnarray. If you want eqnarray, use Edit->Math->Make eqnarray. It is also possible to return to previous behavior by putting bind "C-Return" "break-line e" in your bind file. It is possible that recent changes to mathed will temporarily break the support for align. If you use the CVS for something, then it is better to use eqnarray.
