And then I ran into a review of the iClever iOS folding bluetooth keyboard. https://sixcolors.com/post/2017/06/iclever-bluetooth-keyboard-review-compact-and-long-lasting-but-not-without-quirks/
So I took the liberty of emailing the author the following
Thanks for a good review of the iClever.
But wait 'til you see the TextBlade keyboard! Check it out at WayTools.com It's real; it will be out soon -- I'm typing on a "pre-release/beta/TestGroup" TextBlade for this note.
* The keys are mechanical switches, with butterflies underneath: nice travel, clicks, etc. It feels great!
* But each of the (eight!) keys is actually touch sensitive to distinguish between the letters on each key (QAZ or EDC or RFVTGB). All that differentiation comes from lots of computing power: each of the three "blades" has a CPU, plus a fourth for the Bluetooth.
* All the "extra" keys are easily accessed, just like the number board on an iOS device, with layers (hold the space bar) or chords (for cursor movement/selection/editing/undo). Really well thought out.
It's size beats everything else.
- For typing, it feels completely full size, but as soon as you go back to a "regular" keyboard it feels like you are reaching for the moon every time you leave the home row. "How can the regular keyboard be SO awkward? How have I been typing all these years?"
- Whe**strong text**n it's time to go portable, pull the three blades apart (from the magnets that hold them together), stack the blades, and it's like a pack of gum! Shorter than a phone, only 1/3 as wide and only half again as thick as an iPhone 7
- I got excited by the portability, but now that I'm using it, it is the single best keyboard I have ever typed on.
Just watch for it, and be impressed; be very impressed.
