Mine is half like that. The whole right half makes nice clicking sounds when I press the keys, which I love, it's easy to type on, but the whole left half is just mushy and squeaky as you say, no clicking sounds at all, so i have to keep checking my words to make sure I've pressed all the keys as needed.
Mine's still tight with clicking all around however it's still fairly new. I have seen a co-workers 8310 with full wobble all over the keys and I'm presuming it's just from age as this individual never uses the keyboard. Like they got a BB just to have a BB or something as they only use voice...
