I have to agree with Lantesh and Dutchmaster, it depends on how one defines "easier." For the "average user" (ie Joe/Jane Rube), the one and only thing that makes Windows "easier" is that if something pooches up, he can take it to any fixit shop. To find a fixit shop that speaks Linux, he has to hit the yellow pages - or else learn to fix it himself, which Joe/Jane Rube typically does not want to do.
But Windows is not "easier" when it comes to setting it up, getting it going, installing and uninstalling programs or hardware, or just understanding how the darned thing works. Once the hardware situation got complicated (LANs and layered networking, etc) and Windows started 'managing' program installs like dropping bags of popcorn, it got a lot more challenging to keep up.
If Ubuntu grows in popularity, it may become easier to find fixit shops that speak Linux, but for now (at least in my area), if you want to run a Linux box, you've got to learn some Linux, because something is going to pooch up sooner or later. That's why it probably won't catch on with Joe Average User, and why I don't try to convince everyone I know to switch over when I'm fangirling about Mint. My reasons for wanting Linux include the usual "want to be free from M$ DavrOS and its box-raping minions", but the most important one is "When my Best Beloved dies, I'm hooped." I want to learn to control my OS and my comp again, I don't want to rely on the fixit shops. Getting it up and running may require an expert or a distro like Mint or PCLOS (not so much 'user-friendly' as 'n00b who wants to get their feet in the water'-friendly) but once in, I find Linux is easier to understand and learn how to work with, and by 'work with' I mean the nitty-gritty stuff like getting integrated onto the household LAN, not just loading a playlist into Rhythmbox. I've learned more about how my system works in the last 4 - 5 weeks than in the last 8 years of Windows XP, despite Linux's rep for having a steep learning-curve.
