That's not what Consequence9 is talking about here (or is he?
)
If you compare Ubuntu with, say, Fedora, you'd see the same ease of use on both. Sometimes, Fedora is even easier, for example:
In the next release, you will be able to dobule-click on a file, and if there's no application installed to open it, one will be installed, automatically. no messing with packages, no googling for the 'best program', you will just get a list to chose from and just have to click.
Or another example:
In Ubuntu, you need sudo or gksu (aka the password box that pops up when you start administrative apps). If this gets too annoying, there's nothing you can do about it. While, in Fedora, there's PolicyKit, where you can give privilieges to certain users (for example, you can give them the ability to install packages without a password, or you can allow them to give others privileges) through an easy-to-use GUI...
THE PROBLEM is that Ubuntu is easy to use, yes, but at what cost? Under the hood, it's messy, greasy, and the like. Let's use your car comparison.
Fedora is like your regular, ordinary sports car; if you can drive, you know how to use it, it has neat extra features, and if you want to you can play around under the hood to make it go faster, but you don't have to. It's not for everyone, but it's easy to get used to when you have played around with it a bit.
Ubuntu, on the other hand, is more like a go-cart car you find somewhere in an old village fair... (ok, that's harsh, I know, but it's difficult to come up with cars to compare with
) It's easy as heck to use, and everyone in the villages use it, but underneath the hood is a horribly contrived engine that is doomed to fail if you use it slightly differently than the use it was made for, and if you want to go slightly faster, the engine combusts and what remains is a puddle of a molten 8% blend of lead.
See where I'm going? And yes, I used extreme examples here, but you get the idea
