Firefox. (Followed by Lightroom and TextWrangler if I could have two extra apps.)

GoogleEarth so I would know which desert island I was on...

The one ultimate app... definitely Dropbox for me

[jeffharris]

My thought exactly.

... and VectorWorks would be it!

OmniFocus to keep organized for the construction of the boat.

That's a tough one... But I'd have to say it's a the between Quicksilver and Things. Quicksilver has become such an intergal part of my mac workflow, it's hard to imagine my mac without it. Things is one of the best programs ever made, and it's made me much more organized and productive. It's simple, beautiful and works perfectly. And the iPhone app intigraton makes it simply indespencable. Such a cunundrum.

Well, that would have to be Photoshop. But for pure functionality, saving time, and freeing me from the mouse--the third-party app I wouldn't want to live without is LaunchBar.

Xcode. Then I can use all that time alone to make some new applications. And have a lot of fun doing it. With Wifi I can look up code examples if I'm stuck, or download PDF books to learn new things.

Xcode isn't a third party app, though. So, presuming your Mac is already equipped with Xcode, what third-party app would you absolutely need?

Assuming all the bundled apps that come with Leopard are installed on the machine then I would pick Apple Logic Studio for my desert island app.

Right, but Logic Studio isn't a third-party app. So presuming you could configure your Mac however you wanted using Apple apps, what one third party app would you be hard-pressed to live without?

Pages. Word is a sad distant memory now.

Scrivener. Best app ever for writing and info organizing.

BBEdit is a great app, but I have to cast my vote for 1Password, which I use countless times daily.

If I could vote for my second favorite app, I'd choose Evernote, which has replaced several apps on my Mac and has become much more indispensable than I ever would have imagined when I first installed it.

It would have to to a web browser like safari or firefox (along with my sprint internet card) - you would then have the world at your fingertips, email, online apps, etc..etc...) My second must have is garageband because I love to write music...

Panorama. My database of choice since the mid-80s. Fast and flexible. Simple enough for a Christmas card list. Powerful enough to share databases with other over the Internet, web publishing, etc.
