And what makes you think that? First off, Ubuntu is Debian based, so every Debian package (well, the R ones at least) is also in Ubuntu. Second, we also provide backports of R for Ubuntu releases down to Dapper. I consider this is rather good support; see

As the README file linked above mentions, we provide up-to-date R binaries for i386 and amd64.

For your other points, I will let more competent people answer.
