My iPhone is white, but you wouldn’t be able to tell. I’ve got it encased in a black & red cover from SwitchEasy. I call it the “Horde” case (from Warcraft if you’re familiar).

The six apps at the “corners” are the ones I use most often: Safari, WriteRoom, Clock, Voice Memos, Phone, Camera

I put these apps in the corners because that’s where its easiest for me to hit them if I’m on the move. I don’t have to scan the screen or carefully aim a finger jab. I just point to the corner I need, most of the time without having to look at the screen.

I find it surprising that out of the hundred million billion apps available 5 out of 6 most useful to me are “out of the box.” The 6th, WriteRoom by Jesse at Hogbay Software, is an elegant app I use quite often that invites me to write as opposed to just taking a note (but I use it for that too).

Facebook, Tweetie 2 (not the most used but possibly the most beloved), iPod, and Omnifocus round out the Top 10.

Shaun Inman’s Fever is a web based, self-hosted feedreader with a rather nice iPhone interface, so its not a true iPhone app. Fever opens an iPhone optimized version of Fever from my server.

Between Fever and Instapaper I never lack for worthwhile reading material. Ninjawords makes it fun to look up words I don’t know.

I work in a distributed office and a lot of our communication is done via IM on a protected Jabber server. This makes BeejiveIM a lifesaver when I’m out of the office but still at work.

Flextunes is great for listening to the iPhone in the car and 1Password is a must to keep the hundreds of sites I need access to available when I’m on the go.

The one thing I don’t do with my iPhone is game. I’m an avid gamer but the iPhone is strictly a work, communication, and thinking device. I do my best to keep my app collection focused on things that will engage me with people, not provide isolation. That’s what the Macbook Pro is for!
