At the start of this year (January 2013) I switched to a Dvorak keyboard layout. I have been slowly catching back up to my QWERTY speed. I decided to make the switch to be more ergonomic when typing. The last thing a software developer needs is a repetitive strain injury. One major pain point has been hitting the brackets ([, ]) keys; on QWERTY these are the (-, =) keys. As an iOS developer, you need to hit those keys all the time. I found myself having a hard time hitting these keys as I needed to stretch for them.
