I appreciate distros that continue to offer 32-bit options. They have given old computers new leases on life and distros like arch allow these users to run the latest and greatest software on such hardware. I feel the days of being able to run a popular Linux distro on "any" hardware (old or new) are unfortunately numbered with many major distributions dropping 32-bit support.
Actually on my ubuntu 14.04 machine due to a bug I do need more than 4GB of RAM to do just that. Since the machine only has 4 GB of RAM I really appreciate swap space :)
