Symbian is a no no for me. Even if it has improved, it's still a big pain in the *** to get anything done on it. It'd probably take me several months of programming and bashing against Symbian's antiquated OS to get access to my email account which is only accessible through openvpn, for example...

On maemo? apt-get install openvpn and copy over the openvpn file for my email account. 2 minutes.

Symbian makes me feel like as if I'm being treated like a 2 year old, getting locked up in a very small playpen with a squeaky ball as my only tool, and then neglected.
Atleast with Maemo I'm getting locked up and abandoned in McGyver's garage.
