Ranked in these QuestionsQuestion Ranking
Pro Easier to learn than QGMLWB
Keeps the ZXCV key in the same place as the very common QWERTY keyboard layout. More familiar than even than QGMLWB.
Pro The layout is basically good for most Latin languages
As vowels and consonants are mostly divided between 2 hands and most words in Latin languages are made of 2-letter (consonant+vowel) syllables, the layout keeps it efficiency not only in English, for which it was primarily created, but in other languages too.
Pro It takes much less effort to type than classical layout
The layout effectively combines not only changing hands methods, and rolling fingers as well, that makes typing a real pleasure.
Pro About the same score on the carplax test as the QGMLWB variant
See the source here.
Pro Reduces load on pinkies
Pro Emphasizes adjacent finger bigrams
Common bigrams are a fast rolling motion, like Colemak.
Pro Minimizes same-finger bigrams
Pro Puts your thumbs to good use
Your strongest fingers are your thumbs. In this layout (unless you have a keyboard with thumb keys) you shift your hands up one row, and you use your thumbs on the bottom row. (Put your index fingers on QWERTY's
I keys, and rest your thumbs on VB and NM) The Ctrl and Shift modifier keys now use your strong thumbs instead of your weak pinkies. (Ctrl shortcuts are especially important for programmers.) The modifiers may contribute more to RSI than letters.
Pro Punctuation also optimized for programming
AltGr plane has accessible punctuation and numbers. The most used are directly under your fingers on the (new) home row, and all the bracket types are paired and in easy reach.
Pro Balances load between hands
Statistically, the left and right hand are used about the same amount.
Pro Easy access to common punctuation and numbers
Programmer punctuation and numbers are accessible without stretching on the AltGr plane. (AltGr is now on the spacebar).
Con Very unpopular
Even rich on keyboard layouts variety Linux distros like Deepin, offering most of existing layouts, doesn't have this one. The situation on Android is not better, moreover if somebody get used to Swift-like keyboards, that do not have this layout, that person will be forced to have a second (e.g. qwerty) layout in mind.
Con Not always worth trying
The layout is great only if somebody uses it daily and a lot, like journalists, bloggers, writers do. In this case inconvenience to install the layout is worth use it. If you primarily use your phone/tablet to write some comments in Internet and other tiny writing tasks having such an unpopular layout on just your PC/laptop could be not justified.
Con Pointing stick is no longer on the home row
Most keyboards don't have one, but if you use it a lot it becomes a bit of a stretch. On the plus side, a keyboard with a pointing stick will have mouse buttons you could remap to thumb keys instead.
Con Hard to orient in a new position by feel
Most keyboards have bumps on two of the keys to orient touch-typists. On QWERTY, this is usually F and J, but sometimes D and K. On some keyboards you can fix this by swapping keycaps. You could also try adding small stickers with enough thickness.
Con Letter keys as modifiers may cause jamming or ghosting
Cheap keyboards designed for QWERTY might struggle with the use of Arensito's letter keys as modifiers. Gaming keyboards with n-key rollover don't have this problem. And any keyboard with proper thumb keys (Kinesis, Ergodox, Maltron) works properly. There is an older version of the layout that keeps QWERTY's home row that you can use on cheap keyboards, but it's not quite as nice.
Con Copy-paste shortcuts are right-handed
XCV are on the right side. This makes it difficult to cut/copy-paste with the mouse in the right hand.
