Hi all, long time lurker, first time poster.
What prompted me to make my first post is the following.
I just bought the new Macbook Air w/Thunderbolt.
Everything's great, except the keyboard.
I always love Apple's keyboard, soft touch, light, and responsive.
Not this one.
Some of the keys are very mushy, some keys are non-responsive if pressed on the edge instead of the center, and some keys are just uneven.
While most other keys are just fine.
I tried to press hard on the problem keys to try to fix it, one or two keys got better, but the problems remained.
Finally, I tried to peek under the keys and found something under the keys!!!
Each of the problem keys has a tiny loose screw under it!
The screws were preventing the keys from pressing down evenly.
I used a tiny tweezers to pick up the screws from under each key.
In total, I picked out 6 or 7 screws.
After all the screws are removed, the keyboard is working fine.
None of the uneven, mushy feeling.
I'm really disappointed with Apple's quality control.
My guess of what happened is that during assembly, some loose screws got spilled on the keyboard tray before being fitted into the case.
For anyone who feels their keyboard on their Macbook Air is uneven, hard to press, or just doesn't feel right, I suggest look under the key to see if there's anything under it. And don't try to fix it, just take it back to Apple Store.
