Kinesis Advantage2 vs Ultimate Hacking Keyboard

Having multiple keys under the thumbs lets you keep the rest of your hands still, and helps prevent reaching. For example, the backspace key on a regular keyboard is way in the top right corner, while on the Kinesis keyboard it's under the left thumb. So, to hit the backspace button you just need to move your thumb while on regular keyboards you need to move your whole right hand and stretch your pinky to reach it.

This keyboard is sculpted to fit the curvature of your hand more naturally than regular flat boards. This helps reduce the risks of suffering repetitive strain injuries.

One of this keyboard's best features is that the keys are vertically aligned in straight columns, so that you're not constantly exercising the muscles to move your fingers slightly to the left or to the right. It makes a huge difference.

The large, raised palm rests provide comfort while typing.

Besides the option of easily changing between pre-programmed layouts of these 3 systems, extra OS-specific keycaps come with the keyboard.

This keyboard has several programmable options, like Macro recording, key remapping or keyboard layout (the keyboard can be changed from QWERTY to Dvorak with the touch of a button).

Because of its size, this keyboard stands firmly on the desk and doesn't suffer from unwanted movement during use.

The keyboard has the dvorak layout built in, so you can switch with a keypress.

This keyboard has numerous ergonomic advantages over a keyboard with a standard layout. Some of them are obvious and some are subtle, but they are synergistic and result in a typing experience that places far less stress on the hands. Learning a tweaked keyboard layout is a small price to pay to avoid RSI (repetitive strain injury).

On common keyboards, both thumbs rest over the spacebar, meaning they can knock against each other. On the Advantage 2 keyboard, only one thumb can press the keyboard, eliminating this problem.

This layout, because of its uniqueness, is perfect to learn touch typing. Even for those that were never able to learn it with common keyboards. It still requires practice to get proficient, of course.

The UHK has a split design, since two keyboard halves result in a more natural typing posture. The halves are connected by a bridge cable, which expands and contracts as needed, occupying minimal desk space. The halves can be merged together as one, which is useful for transportation purposes or if you happen to prefer a one-piece keyboard.

Through the use of an app called Agent, users can configure the UHK to their liking.

You can attach trackpoint, trackball, trackpad and additional key clusters to the board. This allows for extensive feature customization, for increased productivity and convenience.

For maximum touch-typing productivity, one's hands should not leave the home row frequently. With conventional keyboards, this is not the case when navigation and function keys need to be used. On the HKB, via a thumb key press, several function layers can be activated, turning the home row keys into function keys.

The UHK is modular and has disassembly instructions embossed onto components and even printed on the circuit board. It records use data, so when key switches have reached the end of its lifespan, users can replace them.
