The same could be said about Windows 8, a lot of people didn't like the changes in it, but ended up keeping it because they didn't want the hassle of changing their OS. I doubt this will bring Linux up in the world as the dominate OS, but I am pretty sure will sway some of the users who don't care to change or end up enjoy it.
Most people have grossly out of date opinions on Linux because they remember using it once and having a bad experience, so they just assume it will always be bad and never try it again. Maybe this will change some more minds about Linux.
Personally for an advent Linux user I am pretty happy to see this, why? Because that means all the parts either work out of the box for Linux or they won't be hard to work with, compared to my boyfriend's HP Pavilion dv6-6c11nr Entertainment Notebook which every Ubuntu past 12.04 won't boot, until you install 12.04, then the drivers, then upgrade. These laptops look like something I can get into.
