First of all there are phones that Android can fly under the AT&T 3G radar and still use the $15 softcap.
Anywhoo... Just off the top of my head:
Symbian gives you much better battery life then Android.
Symbian doesn't have the annoying "Force close" messages that you see with Android. (Heck I sometimes get that with Google Maps so it's not a 3rd party app thing)
Before Froyo (and yes I am going there since more than half of Android phones are currently Eclair or less) Symbian beats it in flash and tethering without rooting.
Symbian does multi-tasking better. Android can only access 6 apps at a time when you press the home screen button.
You already went "hardware" and pointed out the camera thing, but I'll take a Symbian phone for GPS lock on over Android too.
* Sure I can go on the other side of the fence and make just as strong of a case for Android over Symbian, but my point is that one OS doesn't truly have a dominance over the other. They both have their flaws.
Finally I split my time right down the middle with both Symbian and Android each week, so I couldn't be any more neutral and the more important point I'm not trying to convert anyone...
