Who are you, and what do you do?
What hardware do you use?
I have a year-and-a-half old 15" Macbook Pro with a matte screen, an iPhone 4, and an iPad 1. The Macbook is in my lap or bag most of the time, though on occasion, I travel with the iPad and an Apple wireless keyboard. I use a Magic Mouse when sitting at my desk at Studiomates.
I carry everything around in a Moop messenger bag; there's enough room for the Macbook, a Moleskin, and a print book. (I still carry those around. I know - it's ridiculous.)
And what software?
I'm still running Snow Leopard, largely out of laziness. I'll get around to updating soon, perhaps. I use Propane to connect to Typekit's Campfire account; we're virtual, with folks spread out between San Francisco and Berlin, so this is where much of our work happens. I'm also routinely on Skype. I often forget that my iPhone is actually, you know, a phone.
I spend a lot of my time in a browser; usually Safari. Chrome is arguably a better browser, but I seem to be sticking with Safari out of inertia and appreciation for its stronger visual polish. I keep Firefox around for testing and because Firebug is still the best way to debug a site. I use 1Password to log in everywhere. It's completely insane how many logins one person can acquire.
Things remains my to-do app, especially now that the cloud sync is in public beta. I like the way it lets me organize to-dos into different projects; when you have a lot of projects, that bit of separation is key. And anyways, I don't try new things frivolously (as may be clear by now); I wait for something to be broken to switch.
TextExpander is like a magical assistant. I honestly don't know what I did without it. I use it most routinely in Mail, for things like signatures, addresses, phone numbers, and salutations. Such a tiny little courtesy it serves, but it's a lovely thing.
I use Photoshop CS5 for sketching layouts and cropping jpegs, and InDesign for working on the books. Editing for the books usually happens in either Word or Pages; I have no love for either, but Word plays nicely with InDesign, so we're a little but stuck with it for now.
I recently started using nvALT 2 to take notes and I'm smitten. The Markdown support, keyboard-centric design, searching, and autosave are all excellent. I'm taking more and better notes as a result.
I use TextMate to code; I don't even really care that it hasn't been updated in a while - it suits my purposes as is. I'm proud to say I use the Terminal for working with Git, though sometimes I still have to ask Typekit's engineers for help remembering certain commands. (They are a patient bunch.)
Nearly everything I work on is stored in Dropbox. I feel good knowing my laptop could be stolen or smashed, and I could pick up a new machine, hook it up to Dropbox, and get back to work moments later. I keep Crashplan installed as an extra level of backup.
What would be your dream setup?
I'm pretty happy with what I have, though I'm looking forward to eventually trading in the Macbook Pro for a 13" Air. I love that each new machine I get is smaller and lighter than the last. I used to think I needed a huge monitor, but now that so much of my work is writing and editing, that's no longer the case. I'd rather have devices that are smaller, more focused, and more comfortably portable.
