(I have 40M It was a very good choice back in the days when affordable disks were around 200MB and were almost completely taken by the OS+user files, so saving disk space was important. But now disks have grown 8-10 times in capacity, and we weren't as good as other to make newer releases of the os take up all the available space. So, dedicating a small fraction of the slice or 2xRAM, whatever is larger, to swap space as a default should go unnoticed by people with large disks, and they will have less risks of running out of swap. I can only speak for myself, but quite often I do installations on a small dedicated system to avoid troubles, and then move the disk to its final place (almost all of our systems use IDE disks mounted on a removable frame; probably more convenient than a laptop, for home<-->office use).
