Pros

You can clearly tell the difference between those troublesome characters like apostrophes and quotes. Each character is clearly (there's that word again) different from each other to make machine reading easier and work for humans as well.
Pro Optimized for a large variety of displays
Glyph design on Noto Sans is well designed and accounts for HiDPI and standard displays.
Pro Open-source
Licensed and distributed under the SIL Open Font License.
Pro Retina-ready
Looks very clean and crisp on retina displays.
Pro Simple and yet beautiful
Simple and beautiful - much like the Windows counterparts such as Calibri and Arial but it's native for Linux and for this reason it looks better than these two with anti-aliasing.
Pro Expansive character set
Noto Sans is one of the most comprehensive fonts in the market, covering an estimated 30+ languages backed by Google.
Cons
Con Font pack might be too large
Because it is so comprehensive, the TTF/OTF packages in ZIP is really large.
