After a couple of months I have actually come to like the typing experience of the new keyboard - when it works.

The keys need constant cleaning. Simple dust/dirt particles that don't really affect the old keyboards are the nemesis of this keyboard.

I have to literally blow into keys to get rid of dust/dirt particles every single day.

Just recently the smaller up/down keys have simply stopped registering presses (unless you press they keys quite firmly). Many other people have this issue too; here is one thread discussing it:

It's so bizarre to have to remap some unused modifier keys to up/down because of a likely design flaw on a flagship product like this.
