For now, I am going to try both antiX and Puppy from a USB drive first. My mind is still leaning toward antiX, but I want to compare both on the actual netbook before installing anything permanently. That old hardware should make the test interesting.

The cool part is that the Atom N455 is fully 64bit capable, this gives you more modern choices.

Not so long ago, I installed Xubuntu on an AMD Athlon 64, it's okay. The problem is that the O.S. can run fast, but it doesn't mean that then everything else will be fast, e.g. YouTube over 720p is a no-go, and trying to navigate new websites is really painful due to the fact that now websites are basically apps.

That said, it's super fun, do it!
