"Rather than purchasing software from a major vendor, UNIX users generally download source code and compile an application on their specific platform, allowing for an application to run on a variety of hardware and operating system variants (assuming theyre in the same general family)."

Who wrote this - Loverock Davidson?

*nix users haven't had to compile applications for years.
The major distros take care of this. The Synaptic package manager, for example, currently lists over 41,000 packages, all of which run right out of the box on debian legacy distros (including Mint and Ubuntu).

While "new" hardware that doesn't get Linux support from the vendor may take a while to be supported, most Linux users simply install - in fact it is becoming arguable whether Linux or Windows more easily installs on diverse hardware (except for pre-installs, of course, where hardware driver support generally goes without saying).
Most Linux users these days wouldn't know the command line if they fell over it. For some reason, many Linux posters on the 'net insist on providing command-line instructions even when GUI support exists - probably because it's easier in an article to show a couple lines of code than do successive GUI screen captures.

Antiquated attitudes like those demonstrated in this blog don't do anybody any favors, except the idiots like the above-mentioned Lovey, who only exists to muddy the waters by outright lies about Linux.

Please, if you don't know your subject, don't try to write about it. You only spread FUD and get your blog hijacked by the fanboys - and nobody wants that.
Do they?
