I'd agree with that, but my Ez predates the time period of this question. :-) I was a fairly good touch-typist before the Ez, but it did take me about 3-5 days of feeling like I was learning to type all over again. Some of that was the thumb clusters, some of that was getting rid of some bad habits. I used to type the "b" key with the wrong hand, which isn't a good option on a split keyboard. I also used to always look at the numbers when I typed them, and I got blank keycaps on the Ez to break myself of the habit. Oh, and I used to always press shift with my right pinky only, and I wanted to break myself of that. I also switched to i3wm tiling window manager at the same time, so I customized the keymap for that. Love the Ez. Though, I did go through quite a phase of "Surely the perfect keyswitch is on the other side of this fence... I'd tried Gaetron Brown, Cherry Blue, Cherry Brown, Kailh Box White. At the office, the blues were just too loud, but I loved the feel. The Cherry Browns were fine. The Kailh I currently have in around 1/3 of the switches in my home keyboard, where I'm not as noise constrained, and they feel fine, and they're probably quiet enough for the office. They feel good, but I honestly have a hard time telling which has it and which has the Cherry Brown. If at all possible, don't go down the "which switch is right for me" rabbit hole...
