Who are you, and what do you do?
What hardware do you use?
I used to have terrible pain in my fingers and wrists before I started using a Kinesis Advantage keyboard with the Magic Trackpad. I used to own an Aeron chair but since moving from Singapore I have settled for an Office Depot look-alike which seems as comfortable.
I try to not acquire too many gadgets or splurge on hardware. Instead of setting up Surround Sound Systems or TVs, I use my 30" monitor for most needs that TVs fulfill, and stream the audio to Sherwood RX-4109 receiver connected to Sony Bookshelf Speakers. When I do need long hours of music, Bose Noise-canceling headphones work for me.
When I am on the go, I cannot do without a universal plug-adapter that works for most countries. I used to have an iPod shuffle for listening to music, but that has been now replaced by the Nexus S.
I read books on my Kindle before I sleep. I have the older 3G version that allows unlimited 3G access on the Kindle in a lot of countries. It was very useful when I took it with me while backpacking in Australia where I was able to - with some effort - check email and be in touch with people I was meeting with for free.
I have an iPad 1G that sometimes substitutes Kindle as my bedside companion.
I doodle ideas for projects or write to-dos/goals when I am offline on a moleskine notebook.
When I need my gadgets on the go, I have a wonderful satchel I found in a second-hand clothing store that holds my wallet, Nexus s, moleskine, MacBook Air, and a power cord.
And what software?
Opera is my default browser. I use vertical tabs and tab groups to organize unread pages. Opera also has a feed reader which I use to subscribe to internal Opera feeds. I use Gmail for personal email, Google Reader for feeds in general, and the Twitter app for tracking several Twitter accounts. I use Adium for IRC and general Instant Messaging.
Gyazo is my favourite no-nonsense screencapture app. I purchased Screenflow which is a very user-friendly video creating/editing app for anything that requires a video capture. Alfred is my QuickSilver replacement and VLC is the default video player.
Spotify is my music app. Dropbox is where anything I need to preserve goes. I don't like storing photos, because they are only ephemerally relevant, whatever few photos I take, go to Flickr. I have Microsoft Office out of necessity of dealing with antiquated documents that I sometimes get sent.
I use zsh with oh-my-zsh. This is where most of my work gets done. I use MacVim for coding. Python's SimpleHTTPServer is sufficient for setting up a local server. For shared testing, I use Dropbox's Public folder if I need to share it with someone else. Any code goes into a git repo that is either deployed to Github or other remote git repos. For quick bug testing, jsfiddle or jsbin are my tools of choice along with Opera Dragonfly. I also have the latest stable releases of Chrome, Firefox, Safari and IE 9 (in an Image using VirtualBox which also has Windows versions of these browsers) for testing.
I recently ported my blog to Jekyll - all 7 years of it! It is now hosted on Github, and I deploy it from the command line. Each post has a link to its source, so anyone can suggest fixes and updates. It seems to be useful as I get pull requests to fix mistakes in my blog post or even make my website faster!
What would be your dream setup?
I think MacBook Air is pretty much all I want in my primary computer. But I would love to have even longer battery life. I wish there was a Kinesis Advantage keyboard that is travel-friendly (or maybe a better wrist-friendly keyboard for MacBook Air).
