I still can't decide. I've only had mine for about 24 hours, but I haven't done a lot of typing on it. I don't have the best typing form, speed, or accuracy, but I do find myself initially making a lot more mistakes.
My hope is that I'll learn how this keyboard needs to be typed on, and I'll meet/exceed my previous proficiency. But all the while, I have to also be using other keyboards, which is throwing me off!
I use a Lenovo ThinkPad X230 for work. When it's docked at my primary office location, I have an Apple Keyboard with Numeric Keypad (silver and white, the wired version). Both of those are excellent keyboards, which totally weaned me off my older obsession with Model-M-style plunger keys.
I *wish* I could make this MacBook my only computer for a while, so that I could get acclimated to its keyboard faster, but that's unfortunately not in the cards :-/
