Who are you, and what do you do?
I'm Joshua Topolsky. I'm the co-founder and Editor-in-chief of The Verge, a columnist for the Washington Post, and I go on late night TV sometimes.
What hardware do you use?
MacBook Air 13-inch, Core i7, 4GB of RAM, 256GB SSD. I don't use an external monitor (though I have recently toyed with the idea of a three-screen setup). I prefer an economy-size hardware footprint.
I use an LG VL600 LTE stick (on Verizon) when I need cellular data.
For a phone, I'm currently using the Samsung Galaxy Nexus (HSPA+ version), and will be switching to the Verizon LTE model when it becomes available. I rarely use a tablet, but when I do it's an iPad 2.
I used to carry a Logitech M555b Bluetooth mouse, but I recently smashed it.
I backup to a Time Capsule which also serves as the router in our house - hey, better than no backup at all. Luckily, most of the truly vital stuff is in the cloud.
And what software?
Overflow and Alfred for launching / quick access to files, folders, and commands. Typinator for text expansion. Better Touch Tool for window snapping (a la Windows 7 - the best part!). Dropbox for storing crucial files I need to get at from anywhere. I use Fantastical for quick calendar additions, and I couldn't live without Slingshot, which is a screen capture utility that uploads right to my server without any bloat. I sync some of my data to-and-from my Mac via Spanning Sync.
For storing images and notes, I use Evernote with associated browser plugins.
I browse in Chrome.
What would be your dream setup?
I am continually working on downsizing my setup. Even though I mentioned the idea of having three monitors on my desk, my real goal is to make things smaller, faster, and lighter. I'm currently on the hunt for a smaller camera and a bag which is perfectly designed to hold just what I need but doesn't look like crap.
I want to carry as little as possible when I'm traveling, and reduce complications when I'm working. I want the gear to get out of the way.
