I agree on this, though not everything that can or should be installed on Ubuntu comes through the Software Center or even as a .deb or apt repo. For things outside of this, a .exe file on Windows has the upper hand. .exe (or .msi) is a Windows universal. .deb and .rpm are not Linux universals.
>Installers can block each other on Windows as well. This point just seems like nit-picking.
And it's frustrating. You will notice I said "it has to be better than 'better than Windows'", because "better than Windows" still means "learning something other than Windows".
I use Ubuntu. I like it. I'm excited to see where they're going. I'm one of the seemingly few people who don't condemn Canonical for their tight-fisted control over their system. But this article is flawed, and I think throwing some constructive criticism into the mix would be helpful.
