I expected to like it or at least to get used to it, mostly because like you I had (still have) good luck touch-typing on a full-sized iPad virtual keyboard. It turned out that the short travel really bothered me and actually focused me on the fact that I much prefer the Apple Wireless (BT) keyboard to the standard keyboard in the rMBP/MBA. I'm not saying there's a right or wrong, just personal preference.
It's a wretched keyboard. Missing keystrokes all the time. Have had it since launch week so it's not that I'm just getting used to it.
I came to start a new thread title "Wretched Keyboard" but this will do to air my opinion.
Its's so light weight that I love it for traveling but my most used key by far is the backspace key to correct mistakes. Multiple corrections per sentence usually.
Anyone else really like the keyboard?
I'm a fan, wish the BT keyboard had a variant with these keyswitches.
Might be because I use touchscreen keyboards so much, the MB keys just feel right for a laptop.
