Splits

After purchasing this keyboard(silakka54), my life was split to two: before and after split keyboard. While it's very hard to give concrete conclusion on this keyboard, I will try to express my subjective feedbacks which I think are pretty much an advantage.

- Thumb keys

Thumbs are the least efficient keys in regular keyboards, because in most cases they are occupied with a single button - space - and BOTH OF THEM. However I can't say I have a maximum efficiency using them. My thumb keys are occupied with the following actions from left to right: Modifier 1, Super, Space, Space, Alt, Modifier 2. The thing is, one of the Space keys could've been used for Enter instead, that would increase my confidence while typing cause I usually have hard time finding Enter with my right pinky.

- Closer Corner Keys (2)

The left red arrow is Escape, the right one is Backspace. The left orange arrow is Control and the right one is Enter, you can compare it with your keys and measure how far they are.
Yes it's obvious because it has fewer buttons than regular keyboards.

- QMK(ZMK if wireless)

Thanks to QMK, it offers a lot of extra functionality that regular keyboards lack such as remapping, layers and macros.

- And Finally... Layers... (3,4)

As you can see Layer 1 has a lot of extra functionality such as Browser Back/Forward, Mouse Up/Down/Left/Right. Mouse 1/2 is for scrolling up and down. Not only that, it's pretty neat to have special keys for Media Play/Previous/Next which will control music or any currently playing media. ▽ key imitates the action of previous layer. Very helpful when used with Home Row Mods from another layer.

Layer 2 is just for home row mods. It's faster to place them in another layer than setting a hold time on your keyboard.

Moreover, ortholinear keyboard(vertically aligned) keys make it easier to locate buttons. But my key caps are a bit against it, so I’m planning to replace them soon(in Summer I hope).

Now, couple of words about disadvantages. My keyboard is wired. That's it.
