On my new MBA 11 on opening the lid (waking up from sleep) more often then not it takes either too long to reconnect to home wireless or just waits for me to select my wireless from the drop down list.

I owned a MBP 13 before this and never faced such persistent problem in that.
 
I've had this problem with mine. I've never actually had it automatically reconnect to the network after waking from sleep, I always have to manually re-select the network. Even then, sometimes it fails to connect if I do it quickly, but the second time it finds it.
 
I've never had that issue with my 11" air. Wi-fi connects as soon as I open the lid (might take a couple secs max).
 
My 2012 Air doesn't do it but my 2009 MBP with Lion does it all the time since getting Lion. Very annoying.
 
You might try "removing" the network from System Preferences and letting it find it again. Also try removing it from Keychain Access and re-entering the password.
