Pros
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 Zero not slashed or dotted
This makes it difficult to distinguish "0" from a capital "O" for example.
Con Font pack might be too large
Because it is so comprehensive, the TTF/OTF packages in ZIP is really large.
