Mine's squishy just 'below' (towards the trackpad) the ports on the left side, like, exactly on that first screw. At the right side, just around the corner with the ir-port, inbetween the two screws. And on the 'MacBook' place like the OP has, it's nothing too squishy though, although when I tried 'pulling' with the finger nail it made a 'clicky' sound.. scary..
The most anoying is the margin between screen and the lower part of the frame of the monitor, the dust my monitor attracts tends to collect there.. Anyone got some cleaning tips? XD
