Be open-minded and you will find a suitable replacement. I have toyed with Anti-X on my wife's 2009 i686 Acer Aspire One Netbook, which has only 1 GB RAM and an Atom 1.6 GHz CPU/GPU. I wouldn't recommend Anti-X as a server environment, but for desktop use it flies like the proverbial bat. The Netbook is presently using Arch+Xfce, but runs Chrome & Netflix efficiently enough to please my wife, which is better than not.
