The question of this thread is if this is the year of the Linux desktop. And because you CAN'T do exactly what you suggested, the answer is no.
Why can't there be a Linux distro that is accessible like that? Why is that so foreign?
That's a topic that really merits its own thread but in the open source world, there is much more potential for issues to come up initially because anyone can write anything. That power and strength also comes with a big inherent weakness.. the potential for things not to work exactly as planned. This, for some people, is intolerable. This is the reason Linux will never take off as a desktop replacement for majority of users, because they simply don't want to spend the effort to figure out why something is failing. Almost every non Linux user I've talked to that has tried to install it has given up for one reason or another because of something drastically simple to fix that would have taken 5 minutes of looking to understand.
It's far easier for Microsoft or Apple to release something that has been tested over and over than it is for something written by one person to be tested at length. This causes issues that the users I'm speaking about to stop dead in their tracks. Here's a good example: all things considered, there is very little motive for hardware manufactures to write device drivers for the home end user. For enterprise class hardware, sure, but not the former. Because of this, a lot of drivers are written by the user base or adapted/reverse engineered. They're not going to be perfect 100% of the time.
It's really like, you can't have your cake and eat it too. You can't have a highly customizable, fast, secure, easy to use, free operating system that anyone can contribute to without understanding that since its community driven for the most part, you are going to have to deal with issues every now and then.
