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.
