I'm Kenneth Reitz, one of the two co-founders of Züm Hosting. I'm a passionate Python developer for NetApp. I typically spend my nights developing a number of open source projects, and my weekends architecting the web.
What hardware are you using?
My sole machine is a 2010 MacBook Pro running a Core i7 processor at 2.66 GHz w/ 8GB of DDR3 RAM. It's 15" non-reflective screen runs at a beautiful 1680 x 1050. It features both a 250GB SSD and 500 GB HDD, for a total of 750GB of local storage, thanks to the OptiBay. I often have it hooked up to one of many 23" LCD monitors. For general audio, I sport a pair of Bowers & Wilkins P5 Headphones. If I'm in a high-fidelity mood, I listen through a pair of open-backed SR-60s from Grado Labs.
For telephony, I have an HTC Supersonic (EVO) running running the Nighty Android 2.2 (Froyo) CyanogenMod v6. This also functions as a perfectly portable hotspot.
I read documentation and play arcade games on a 64GB Apple iPad (wifi). I play a PSP Go solely for Castlevania: Symphony of the Night.
I have a large number of very powerful Linode servers at my disposal for various projects and builds.
My system is backed up regularly to a cheap 1TB Western Digital drive. My media archives are backed up to a 1.5TB Seagate drive.
My media exists on a NAS attached to my Netgear WNR3500L router. My code is backed up to various Git repositories local and across the net. All web projects and databases of relevance are backed up to Amazon S3 on a nightly basis, along with all my tweets, Flickr photos, and Gmail messages.
And what software?
I develop and live on the latest build of Snow Leopard. My main Python environment is the latest 2.7 release, along with well managed virtualenvs for all other releases via Buildout.
I also employ a very large number of virtual machines, via VMWare Fusion 3. I have a particularly efficient XP VM that is always up, providing me with OneNote 2010. I'd do anything for Mactopia to port OneNote to OS X. Anything.
My development environment consists of TextMate + PeepOpen, [most recently] PyCharm, SequelPro, Titanium Mobile, Transmit, and GitX. I love using HTTPScoop for request sniffing.
On servers, I typically run the latest Ubuntu Server release, or CentOS (but only if I have to).
My audio production work is carried out in Adobe Audition CS3 and FL Studio 9. I use Adobe CS5 Master Collection for light design work and photo retouching. Photoshop Lightroom for kosher photography dark room work. I've been meaning to get into Fireworks for wireframing, but haven't had the time as of late.
As for architecture work, I utilize OmniGraffle for diagraming, Mockingbird / Balsamiq for mockups, and MindNode Pro for mind-mapping.
For note taking, as mentioned, I use OneNote 2010. Nothing compares, except my Soft Large Squared Moleskine Notebook. My tasks are managed with Things.app. I can't wait till they roll out proper syncing. If they don't do it fast enough, I'll be switching to Macman's Taskforce.
I use Kindle for purchased books, and iBooks for PDF reading on the iPad. I consume Google Reader via Reeder, the most beautiful application I have ever used.
My music library is provided by Spotify at offline, 320KBPS Ogg Vorbis goodness. In the rare occasion that Spotify is missing an artist, I use 320KBPS MP3s and FLAC recordings for the ultra-special tracks (e.g. Liquid Tension Experiment). I buy my MP3s from the (wonderful) Amazon MP3 Store. I keep my video library nice and organized in iTunes, regardless of format, with iFlicks.
I stream 1080 videos, NetFlix, and BlueRay Disks with a Play Station 3 Slim. I play emulated retro video games Wii. Best $200 I've ever spent.
For communication, I use iChat + Chax, Linkinus, Echofon, and Skype.
What would be your dream setup?
No power chord.
