2) ubuntu is debian-based and features dpkg, which a large majority of linux software is packaged in. on arch, if it's not in a repo, you need to install it from source.
3) The arch linux community is also
full of elitism, while Ubuntu's forums welcome newcomers warmly. And either way, most problems can be solved with a Google search. not to mention ubuntu, like plenty of distros, have a corporate backing to them which is greatly beneficial, such as Fedora having Red Hat and openSUSE has Novell. arch is COMPLETELY user driven.
4) again, elaborate? canonical's online documentation seems damn fine to me.
5) of course there are many fixes. they're all for stuff that you don't need breaking in the first place.
and in arch's case, it depends heavily on the user's knowledge of linux's inner workings. ubuntu requires very little command line, which can be scary for newbies.
