I am a everyday user of my 32 bit laptop. It works already from 2006 and nevertheless, it is in pretty good shape - battery works at least 4 hours and SSD gives a good performance boost. I am doing with it all my office works and web surfing. Also I love its 4:3 screen which allows me better to read documents and books, specially in book-view mode. Just watched with it two movies on Youtube.
I think, this is how most of people uses their computers anyway. Its not a worth to throw off my 32-bit one and buy 64-bit one and use it same way without any radical differences. Unneccessary hassle. When telling abut software development, the older computers fits better for software testing and optimizing purposes.
So anyway I will continue to use my current 32-bit oldie. When talking now about Manjaro32, then I agree to dispose it. Nowadays 32-bit computers are so rare, that I think it is better to have only few, but good 32-bit distros, rather that waste resources to many different of them. We already have Archlinux32, so i dont see any reasons to maintain Manjaro32 in parallel. Of course, if someone will pick up and continue maintaining it, I gladly would keep using Manjaro32.
