Ranked in these QuestionsQuestion Ranking
Pros
Pro Comfortable and ergonomic
The 227 is designed ergonomically, so it fits user's hands naturally, making it comfortable to use.
Pro Key layout customization
The 227 key layout can be altered: users can move functions between keys as they please. Settings are firmware-saved, so they apply even if the keyboard is moved to a different computer.
Pro Non-staggered keys for easier typing
This keyboard's keys are arranged in a non-staggered way. This allows for a more efficient, easier typing process.
Pro Detachable palmrest
The 227 keyboard has a detachable palmrest, for hand support during use. This helps reduce harmful strain.
Pro High quality mechanical switches
The 227 uses Cherry MX Brown switches, which are very reliable and accurate. They're quiet, soft and give a nice tactile feedback.
Pro Version with blank keys looks sly
There's a version that comes with blank keycaps, which looks great. It also helps learning how to touch type.
Pro Large Alt keys
This keyboard has large Alt keys, which is useful for key combinations that use Alt.
Pro Great for when Assembly offers too much abstraction
Pro Simplicity
The SuperCoder 2000 offers a simple, clean layout without fancy extra features like a numpad or media keys, enjoyed by some people.
Pro Great key spacing for error free code
The spacing between the 0 and 1 keys is larger than traditional keyboards. You'll rarely fatfinger a 0 when you mean to enter a 1.
Pro Minimalistic design
Unlike some other keyboards, the SuperCorder has a clean, simple white look, which can be less distracting and favored over more flashy, gaming-oriented keyboards.
Pro Air cooled
This keyboard is air-cooled, which means there is no noise generated by cooling fans. This makes it great for quiet work environments where fan noise could be a nuisance.
Pro Saves desk space
This keyboard has less keys than a standard 104-key keyboard, and thus is smaller and takes up less space on your desk. This makes it great for compact work environments.
Pro With fewer keys, you are less likely to hit the wrong one
Pro Especially good for professional coding
Pro Programming dream
I managed to recreate GTA V while writing my own engine just using binary in just the space of a week with this keyboard. Would recommend.
Pro Vetted by Jeff Dean
Pro Does not allow for errors
The lack of a delete button forces you to progressively learn how to always produce error-free code. This is an enormous advantage when it comes to the learning process.
Bonus: you can fix logical and mathematical errors with subsequent commands.
Pro Great tool for truly low level programming
Considering the performance overheads of managed code, go beyond assembly, back to basics.
Pro Great for gaming
The 3 key design is perfect for rhythm games such as OSU.
Pro Completely universal cross-platform. Programs in any language.
Pro Can be used for gaming too
Can play Starcraft 2 with this, although only supports playing Protoss.
Cons
Con Cable hassle when carrying around
Since this keyboard's USB cable is not detachable, there's always cable mess to deal with when transporting it.
Con No backlit keys
Unfortunately in dark rooms this keyboard becomes increasingly challenging to use. Although, assuming you know how to locate the home key you should be fine. More of a nitpick.
Con No Caps Lock key
Con No wireless version available
Would be the perfect keyboard if only it was wireless.
Con Requires powered-on machine for use
Inconvenient for use when you must write code without electrical power or batteries available. Would recommend a pin and magnetic storage medium in that case.
Con Uncomfortable for two-handed use
While working with two hands, this keyboard is too small and key spacing is too narrow.
Con User Security
No password option.
Con No Backspace/Undo
You can't backspace binary code.
Con Can only type binary code
This keyboard is useless for typing anything other than ones and zeros, which makes me wonder why it's even on Slant.
Con No android support
Con No support for Mac OS X
This keyboard offers no software support for Mac OS X. It only works with Windows or Linux operating systems.
