>Those keyboards broke because of small dust particles, nothing related to liquids, people are using the laptops as before but this time the keyboards are to fragile.

I didn't specify which keyboard. Even mechanical keyboards can be affected by this. I wasn't referring specifically to the new Macbook butterfly keys.

The amount of dust that would be necessary to incapacitate a mechanical keyboard would probably coincide with the amount of dust necessary to fill all the space of the key travel.

Most mechanical keyboards are basically protected from dust entering the physical area of the switches due to a hat-like dome formed by the keycap itself. On top of that a lot of the switches are closed and rated for minor dust exposure (cherry's can with stand some water and dust internally)

I've never heard of a keyboard failing because of dust with the exception of Apple's MBP keyboards.

Again, I didn't specify dust. My point was that keyboards are susceptible to getting sticky from different ways. It's an accepted potential issue.

Most well engineered keyboards are splash resitant and easy to clean if they get sticky.

But that is not the problem. The problem is really that the keyboard is susceptible to a problem that 99.9% of other keyboards are not, even on laptops.

A complete failure of operation because of dust is inacceptable on a device that will be expose to a lot of environmental dust from being in laptop bags or having people carry them around to eat or similar.
