It's nice to see I'm not alone! I haven't really used a 'legit' debugging tool since my days as a C# developer. And that was because how easy debugging was in Visual Studio. I have yet to find something that just works, as easily. (I imagine XCode works perfect too, never programmed in Obj-C though).
Gdb works well for embedded Linux targets, provided you have Ethernet or a serial port. You can bring gdb up I the target and then connect the host to it and debug from there. If you're using an Eclipse-based tool then you can set that tool up to connect to a remote gdb.
At least, that's how it works when I'm developing under Linux. I'm not sure about Windows or Mac OS.
