when many big distros even discarded non-pae i686 for some time?
I think a huge part of PC users has no more than 4-6 GB RAM. Why refusing them the advantage of not having to deal with lib32-… troubles (sometimes hell) for some theoretical (well, even a real 10-20% speed penalty) disadvantages of PAE which are of little to no importance for the home user?
Other than that, Arch is great. Thanks.
