Personally, Arch has been really unstable for me, although I have a newer ATI graphics card and am trying to go it with the open-source drivers, so that's my problem.
In general, what people mean about Arch's flakeyness is the general maintenance involved with staying up-to-date, and reviewing all your pacnews/pacsaves.
it is, but every now and then a software update will break something, or something will conflict. it's fine, but i find overall stability is a little bit of an issue, which i didn't use to mind, but these days i do. even simple things like making sure my machines are on the same versions of things, or expecting to install something and it just workâ˘
