Would 512 be okay, or should it be 1GB?

Dunno. It depends on what you're gonna use it for.

A consultant of ours said his Powerbook (17 inch) was very good for running multiple virtual PC's. If you wanna do the virtual PC thing then I'd throw as much RAM at it as you can.

Heavy-duty graphics or programming could also use lots of RAM.

I have absolutely no clue how to make X11 use the tcsh shell. I don't even know what that is.

A shell is just the software that interprets the commands you type into a terminal session/window. There are several popular ones.

I'll try to find how to change it - it should be simple...

In the meantime, instead of the

setenv DISPLAY localhost:0

command, try using

export DISPLAY=localhost:0

I think that's the correct way to do it. Apparantly one of the biggest differences between tcsh and bash is that in bash you don't use setenv.

OK, here's a question... if you change the default shell for OS X, does that change also change the default shell for X11?

eta: Crap, I should do some work. In the meantime, here's info on changing shells: [link]

You can't change the default shell for OS X or for X11, you can change the default shell for a user.

I'll try all this when I get home, for sure. Thanks muchly!

You can't change the default shell for OS X or for X11, you can change the default shell for a user.

Yeah, that's what I meant. Of course, I didn't say that, so thanks for the clarification....

So what was the question then?

Is there just one thing to change? i.e. does changing the default shell for a user in the regular OS X environment also change the default shell under X11?

Yes.

Oh, I was assuming that was not the case. That makes things easier. The link I gave above has instructions on how to change a user's shell that should work for Theo, then.
