RedHat is one of the most widely used Linux distribution, at least in the corporate and academic sectors. It's been around for years and after all the shit they've gotten from users trapped in RPM "dependency hell," you'd think they'd have learned SOMETHING by now, right?...Right?
When I first entered the Linux world a decade ago, my desktop experience was pretty was pretty abysmal: just xterms started by running the 'startx' command. It wasn't until much later, late 2000, that I started using KDE. I was in love.
Linux has come a long way in the last 10 years, especially when it comes to the desktop. Distributions like Mandriva, Ubuntu, and Fedora are leading examples of success in the Linux desktop world. But despite the excellent work these distributions and the thousands of open source developers have done, mainstream Linux adoption on the Desktop is marginal at best.
It's not that Linux isn't ready or the technology isn't there yet. It's all about implementation.
