I’ve been using a Sofle split for almost a year, probably in about 30-40% of my typing. Despite tweaking my setup as best I can, I still find the experience difficult.
One issue that seems to have a big effect is that I still think of the position of mouse in my dominant hand and keyboard with my other hand as useful.
I use it often for everything from casual surfing to editing. For example during editing you’re often selecting text with the mouse and doing some minor editing with your other hand. Split keyboards seem to really remove this efficient option since both your hands need to be used most times.
A lot of people who extol the benefits of split keyboards are comparing to traditional keyboards when your tasks are static.
Ok so I use a split since two months and the switch is certainly not automatic but the solutions are fairly simple. I’m a good exemple of a user scenario that requires a lot of one-handed operations because I mainly edit text and not writing it and I use a lot of GUI related to graphic work (illustrator mainly but also photoshop). For the following process, I should make clear that I’m on a Mac and it’s clearly a big plus since this platform promotes consistent patterns of shortcuts.

I should mention that I use Colemak and that it certainly help compared to layout leaning toward hand switch (Dvorak, Bepo…). But if you’re on QWERTY it should be good.
