I'd used Excel Connector ever since I started working with Salesforce, back in 2005--I'm such a fanboy, I've added to its source code and released a custom version of it. 

But let's face facts: Enabler for Excel is better. I banished my Excel Connector menus and haven't missed them yet.

Huge thanks to Jeff Francis for alerting me to it! (He recommends trying out its Page Layout analysis capabilities.)
