I have already pledged for the 104-key model this morning and now they are here in #1 Product Hunt! What a coincidence. I am so excited to try this keyboard on my Mac.
The biggest downside for me is the layout. Coming from a UK MacBook, I hadn't considered how big the transition is to a US keyboard layout. I actually thought the UK MBP had a US keyboard layout on it due to the placement of the # symbol, but it turns out there are still differences. The most noticeable is that on a UK layout the return key takes up two rows and is narrower, whereas on the US layout it takes up one row and is wider. This means that whenever I go to hit the apostrophe key, I hit the return key instead. Typing messages with don't/it's/can't/won't in them usually results in the message being sent before I've finished it. This is primarily a muscle memory thing, not a criticism of the product, but for any other backers/buyers from the UK who type a lot, be aware that you will accidentally hit the return key a lot. You will also have to re-learn how to tab between application windows because the ~ key has moved. And fn+backspace is close to impossible because the fn key is on the right-hand side. There is a delete key though. Battery life for me has been approximately 10 days with the keyboard backlight completely disabled apart from at times when I accidentally hit the light button. Pro tip: instead of cycling through lighting options, just hit F5 a bunch of times to dim the lights again.
