Pros
Pro Uses the same fingers as QWERTY for most letters
Norman keeps 22/26 letters in their original QWERTY finger, making the transition easier, and, according to many tests, does so without much loss in ergonomics.
Pro Keeps many common QWERTY shortcuts intact
Common shortcuts, such as ctrl + z, ctrl + x, etc., are kept in their original positions without much loss in ergonomics, making the transition easier.
Pro Feels fast and comfy
Pro Focuses on the keys easiest to reach for the human hand
Like Workman, Norman takes human anatomy into account.
Pro Designed using normal keyboards in mind
Unlike keyboard layouts such as workman that are desgined to be used by matrix keyboards, norman is made to be used by a standard keyboard.
Pro Favours the right hand
Unlike other layouts, such as workman, norman favours the right hand due to it usually being stronger than the left.
Pro Punctuation is also optimized
The comma and period are more frequent than KVJZXQ.
Pro E on the thumb
E is the most used English letter by far at almost 13%.
Pro Highly optimized for frequency of use
This includes di- and tri-graphs, as well as the individual letter frequency.
Cons
Con Bad on SFBs
Lots of same finger bigrams (when 2 keys are hit simultaneously by one finger like the qwerty "ed".
Con A very small user base and community
Con Designed for right handed use
The Norman was designed with right handed use in mind, making it a less attractive choice for left handed users. However, tests done by some users (can be found in the comments) suggests that the Norman layout might be balanced.
Con Scores worse in ergonomics using the Carpalx test
Norman, although scoring better in travel distance, generally scores worse in the Carpalx test than layouts such as Colemak. See the source here.
Con Requires a physical keyboard
The Maltron layout requires an expensive physical Maltron keyboard. Most layout options are a simple change in software, to remap existing keys. (Touch typists mostly don't look at the labels anyway.) But there's no way to add the required thumb keys for this layout in software.
