Given all the negative press, I thought it worth saying on here that it has really grown on me the past few weeks since upgrading my MBPro.
I even like the keyboard too, (whilst I hoped to hang on for a 13" revision like the 16" but the burglary forced an upgrade!)
It is a useful hardware feature and the extension from BetterTouchTool, whilst not for everyone, (I've found it a little fiddly) adds lots of functionality.
I thought I'd hate it, but it's helpful in lots of ways as it adapts to each app. I thought it was a gimmick but when I'm plugged in to a monitor using external keyboard, I actually miss it!
But, as now with the 16", I wish the esc key was physical. I've got used to it, but I don't like it too much!
Just thought I'd share it here, in case others were in two minds, too.
