Also not OP, I gave up Arch around 2011 as well after I wasn't able to mount a USB pendrive at the uni, as I was rushing somewhere. This was embarrassing and actually a serious issue, took some time to fix upstream and finding workaround was also annoying. This is when I gave up on it and never looked back, but I did, indeed, learn all about Linux internals from dailying Arch for 3 or so years.
