Topre Realforce 104UB vs Microsoft Sculpt Ergonomic Keyboard

Topre switches are a mix between mechanical switches and rubber dome switches. They have mechanical components, however they are covered beneath a rubber dome which protects the switch. They bring a mechanical feel, and mix it with the durability of a rubber dome switch.

Variable weights under each specific groups of keys was done in a bid to prevent RSI (repetitive strain injury). For instance, the groups of keys that the pinky finger hits are much lighter/softer than the rest of the groups of keys that are pressed by the rest of the fingers. Variable weights are achieved by having either heavier or lighter rubber domes. Whilst this idea is very useful for normal typing, for gaming it's not so great: for instance, when dealing with First Person Shooter games that requires WASD keys, those sets of keys feel very light when fingers other than the pinky are used to actuate them.

Silenced Topre switches are designed for those who do not particularly like the sound of keyboards being tapped on or for those who may be concern over disturbing others when using a noisy keyboard. Silencing is done mainly by placing a material that absorbs the sound of the slider when it makes contact with the slider housing. This thereby prevents excessive noise when the key has been released after it has been actuated. The overall effect of a silenced Topre is quite astounding as it may give the impression one is on a cheap keyboard (obviously, the reality is actually the opposite).

PBT (polybutylene terephthalate) keycaps last longer than other keycap materials, and are more durable. They are more expensive than ABS (acrylonitrile butadiene styrene), which is why they are less commonly found.

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.

Thanks to the scissor switches used, this keyboard is very quiet.

The Sculpt's keys absorb impact quite well, avoiding injuries related to repetitive movements.

This keyboard has a comfortable, cushioned palm rest.

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.

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.

Using this keyboard with vim bindings you can sometimes nearly forget there's a keyboard between you and the editor.

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.
