Guess it not only feels flimsy, it actually is.
Getting more and more driven away from the TB model the more I think about it.
I'm fine whatever your choice, but a small note here: in my experience it's not flimsy, it's simply very sensitive to dirt.
Flimsy would mean to me that it quickly breaks in pieces. But my keyboard never broke, it feels very sturdy to me. But the sturdiness comes from the extremely small space below the keys. So any crumb from a cookie or a sandwich will clog up the keys, and need compressed air to clean.
