Let us know how well this works, if you're doing it. While I can see advantages to having a small, unobtrusive handheld (a cell phone) to do this, my preference would be to have code on something like an iPhone or iPod touch, at least, for the slightly larger screen size and readability's sake (like the demo I saw from DefCon last year, I think it was.) I'm not a fan of trying to make sense of things on uber-tiny screens, with limited text entry capability, unless I'm going in with something pre-scripted, specifically for the task at hand, etc.
I DO have BackTrack loaded on my oQo 2, and even that, if I'm not prepped beforehand, is not the most convenient (even though it DOES give me the slideout keyboard, etc, and a nice small footprint to carry in and out, unobtrusively.) It also has great support for packet injection, etc.
So I'm always interested to hear others' experiences with handheld devices and BackTrack / hacking distros and tools, and am open to trying more of them myself, if they prove to be easier to utilize, for their small sizes.
