Something that everyone has ignored is the fact that if you have physical access to the PC you can always force a single user boot from the boot manager, and ...

So a good, complicated password is only vital, IMHO, if you have a PC that is not firewalled, and/or has ports open to the net at large.
If you want to store data securely, then realying on your login is not a good idea at all... rather use a proper encryption option like gnupg or similar, or even better, Truecrypt (which creates and mounts encrypted partitions/files). Truecrypt encrypts data on the fly, and - depending on the algorithm that you select - can do so fast enough that you will not notice a drop in HDD access speed (I use two-fish which clocks at 59Mb/s on my somewhat outdated P4 3GHz (hyper-threading) and over 100Mb/s on my core2 duo laptop at work).Respectfully...

The moving clock K' appears to K to run slow by the factor (1-v^2/c^2)^(1/2).
This is the phenomenon of time dilation.
The faster you run, the younger you look, to everyone but yourself.

I was thinking encryption only really slows down access to data when physical access is obtained ...

If you have physical access the only thing that can work is encryption as you say, and only if the attacker doesn't work in the NASA and doesn't have a cluster to break it. You don't even need to login or change the password, just take the HD and put it into an external case and you got access to everything. So if that's the case, the whole thread is moot.
However, for the regular user:
In general, passwords that you have to write yourself are never secure. And are just a minor annoyance, designed so you can go to the wc without your children screwing whatever you were doing. Provided enough time and physical access only encryption can help.
