The font is available on machines running Windows Vista, Windows 7, Windows 8, and Windows 8.1, as well as part of Microsoft Office 2007 and Microsoft Visual Studio 2010. Otherwise it can be downloaded from Microsoft's homepage. It can also be set up on OS X machines with instructions on how to do it available here.

Pro Contains many glyphs
This is useful for those who wish to use different languages.

Cons
Con Not free
Consolas costs 129€ for personal use, but you can get it for free (as in beer) bundled with some free MS products (example).
Con Font size can't be changed gradually
Letter height is the same for 9 and 10, and for 11 and 12 pt. When switching from 10 to 11 pt, letter height changes abruptly (whereas line height changes gradually). This makes it impossible to choose exact letter height on a standard display. Size can't be set to 10.5 pt, for example.
Con Italic font is very different
The italic font (often used for comments) feels jarringly different to the regular one - especially on the "g" and "f" and "l" (lowercase L) glyphs.
Con Highly aliased with ClearType
Consolas is specifically designed to work with ClearType antialiasing, so it becomes highly aliased when ClearType is not turned on. This can be alleviated to a degree with any basic grayscale anti-aliasing.
As an OpenType relative of Consolas, Inconsolata works well without ClearType (Inconsolata-g being the most popular variant).
Con Small 'L' is too similar to digit 1
You can tell the difference when they are close together, but when used apart, it can be a bit hard.
Con Poor legibility with small font-sizes on non-hidpi screens
Consolas in the 9 to 13 pt range is hard on the user's eyes with any monitor that's 1080 p or below.
Con Starting from 9pt, "!" is too similar to "|"
Con Entails costs
Only the basic version of Skyhook mono is free.
