It just seems like it would be on par with buying a brand new computer to get your writing done, then installing DOS because the web browser was just too alluring.
All that said, I ended up taking this to the opposite extreme: I've set up my phone to be cross-linked into as many work-related systems as possible, so that I can take better advantage of those little "in-between" moments during my work days. Build's compiling? Get an alert when it's done. Waiting for a coworker to get out of a meeting? Get an alert when they ping your name in IRC/Skype/GChat. Not having to sit in front of my computer waiting for asynchronous blockers to resolve means I can retreat to the porch, or the living room, or the park up the street, without having to worry about coming back to find something's on fire. Additional apps allow for limited on-the-go debugging, interfacing with systems and the like, so that I can continue being away from my computer if the situation isn't severe enough to require my actual physical presence at a keyboard and larger screen.
