AGREED!!! & relieved x2!!
Will check mine now (Mid 2011 27") I am very careful now about what I install since the 10.7.3 debacle...
----------
Not applicable...I'm relieved really. Not having any issues so no update is good.
Geez...I am still feeling the after effects of that fiasco with the Lion 10.7.3 update! Unfortunately I was one of the 1st to have the CUI??? mess!!!

....Luckily my Time Machine backup saved my butt!!
Like you, This update DID NOT apply to my machine.
Forgot to mention that after 2 weeks I tried to d/l the 10.7.3 combo updater, (the not mentioned 2nd build) I was greeted with a "checksum error" when trying to install it. (Not my router, and a fast Inet connection).
My only solution was to use SU, and it actually worked just fine this time around. To be really honest, I would love to skip many of these updates, but future updates seem to depend on keeping everything current...oh well, could always be worse!
After having basically
no issues with my last 2 iMacs; (my current one is a 21.5" i5, mid 2011 model). I am feeling the same way that you do!
Now I dread it when SU runs!!! My only answer is to wait for a week or 2, before undertaking anything major update wise....Now when they mess with the firmware..... That gets me a bit nervous!!
