I am loving Linux. Just have a look at this screenshot below, what with Linux Ubuntu 14.4 LTS cloned to an external Disk Drive and running very fine on my DELL XPS 17 with boot from USB.
All the Programming, Social, News, AV prowess and Linux chugs along nice and fine !
I also like the browser like Multiple Tabs that can be opened in the Nautilus File Manager ! Calculator App is also pretty advanced with Unit converter, and Currency Converter built-in it.
I also love the feature of Social Apps Plug-ins right on the desktop. You visit Twitter, Facebook, Google Plus in browser and it prompts to install the desktop app and once installed you get it in the Ubuntu sidebar!
So if you are still not on Linux, get it fast and enjoy your Linux !!!
