Comment 110 for bug 930447

Including a PAE only kernel with the default ISO significantly and unnecessarily limits scope for installation of 12.04, and going forward, Ubuntu generally.

Many good spec machines don't have PAE. A notable example being Centrino laptops.

Within weeks (or days) of a distribution being released, a new kernel is generally available for update. Perhaps the sensible approach would be for the package manager to install the latest PAE kernel on first update IF the CPU supports PAE.
