Ranked in these QuestionsQuestion Ranking
Pros
Pro Tactile and "clicky" buckling-spring key switches
Buckling-spring switches are hardly used anymore, but they give some of the best tactile response when activated.
Pro Very sturdy
Although heavier than a modern keyboard, this keyboard is built like a tank. There is no flex, and the components were built to last.
Pro Solid construction
Quality construction, good materials.
Pro Clear separation of key groups
Pro Attitude
Clearly signals that I'm serious about what I do and how I do it.
Pro Removable / replaceable keycaps.
With a hook beneath the caps that you have to get to, you can detach those keycaps and replace them with others.
Pro Ergonomically shaped
Our hands naturally rest angled when in front of us, and this keyboard has been built to conform to that, rather than having us awkwardly trying to straighten our hands on a regular flat keyboard, putting strain on our wrists. The keyboard is also curved into a dome shape, which contributes to its ergonomic shape.
Pro Quiet
Thanks to the scissor switches used, this keyboard is very quiet.
Pro Low impact keys
The Sculpt's keys absorb impact quite well, avoiding injuries related to repetitive movements.
Pro Cushioned palm rest
This keyboard has a comfortable, cushioned palm rest.
Pro Clean look and flexible positioning due to wireless connection
This keyboard connects wirelessly to the computer. This offers many benefits, such as a clean, tidy look (no cable mess) or a flexible positioning (greater use range). On top of that, it doesn't occupy one of the ports.
Pro Number pad can be placed where it is more convenient
Since the number pad is a separate part from the main keyboard, its position can adjusted and it can be moved out of the way when it isn't being used. This allows for a more ergonomic mouse use, since it can be placed closer to the keyboard, just like in a tenkeyless design.
Pro Very comfortable
Using this keyboard with vim bindings you can sometimes nearly forget there's a keyboard between you and the editor.
Pro Slider switch for special functions
Rather than the usual Fn key that needs to be pressed in combination with other keys to activate said key's secondary functions, the Sculpt has a slider switch that does this. This makes it easier to default to those functions.
Cons
Con Noisy to type on
Floss mod is available for the Type M to make the keyboard a little more quiet. However, since it's still a mechanical keyboard, it will be noisy. This keyboard will not be appreciated in the office.
Con Very hard to acquire
Out of stock for decades.
Con Ugly as hell
Con Some driver issues with USB-only computers
Using a PS/2 to USB adapter can kill rollover.
Con Very large
Measuring nearly 20'' x 8.5'' x 2" ( 50 x 21.5 x 5 cm), this is a very big keyboard. It will be hard to fit into a minimalistic styled desk setup, and might even be too big for some smaller desks.
Con Lacks some modifier keys
The Model M lacks both of the meta/super/cmd/Windows (depending on the OS in question) keys and a menu key.
Con Functions keys are not easy to use
The function keys are too small.
Con Bad separation of key clusters
The Page Up, Page Down, Home, Insert, End, Delete and Arrow keys are squeezed together, right next to Enter, right Shift and right Control, without any physical barrier/marker to separate the two key clusters. Since this is not an usual layout, it is disorienting for users.
Con Less durable than flat keyboards
Because of its shape and thin design, this keyboard will break more easily than the typical, flat rectangular keyboards. This makes it less portable, unless you're very careful.
Con The key switches used aren't ideal for long typing sessions
The switches used are scissor switches, which are the ones used in many laptops. They provide shallow keystrokes which don't give the same feedback as a mechanical keyboard. These keys need to be bottomed out in order to activate, which creates some strain on your finger's joints as they are constantly hitting the bottom of the stroke. Scissor switches are also known to be less accurate than other keyboards.
Con Some keys aren't very reliable
Some keys (like Backspace or Enter), if not pressed perfectly perpendicularly, hit the shelf of the frame and get blocked on their way down. This means the stroke isn't registered and, on top of that, feels awkward. On the (slightly) bright side, this awkward feel acts as feedback that the key wasn't fully pressed.
