Viewport size Q for those with a widescreen Mac.

At the moment I'm short of access to a widescreen Mac. I'm trying to
find out what the pixel size of the viewport is on Safari when you
have it maximised with tabbed browsing and the standard set of
buttons, menus and toolbars in place.

I've done the same exercise on Firefox and IE7 on Ubuntu Linux and
Windows, and for a nominal 1280x800 widescreen display you get a
viewport of 1260x570 on Firefox and 1258x652 on IE7.

If you've got a Mac and can measure this for me in 1280x800 mode, I'd
be very grateful.

If you're resolution is higher than this I'd be even more interested
in the results.
