YES.
From a noob point of view, without getting into the technical details....
Ubuntu which is based off of Debian... Is very user friendly. It's one of the most complete Linux builds (distros) which will come with drivers for old and new hardware, just like windows. So out of the box, it's likely already working for you.
The user interface is very user friendly. And installing applications (the process) has become as easy as installing a program in Windows or Apple. But they're making it even easier by offering an app store, so its as easy as picking an app and just installing it (much like how you would in a smart phone).
You can try it using a Live CD without installing Ubuntu. The CD boosts and load it into memory (RAM). You'll basically be using a "temporary" "virtual machine". It maybe a little limited and slower on a Live CD without installing it, but you should get the basics.
Ubuntu can also dual boot along side Windows (and I think Mac OS as well, but don't quite me on that). The install is almost completely automated. As automated as it is to install Windows 7 or Windows 8.
