I remember, when the first Titanium Powerbook was released, having something akin to what I must describe, simply, as a "Writers Moment of Nirvana".<p>I'd just received the machine, a reward for a schedule met, on a Friday afternoon. Charged, ready to go, I put it in my briefcase (in 2000, this was a phenomenon like no other), and .. left the office. With the power supply, box, etc.<p>So I had a weekends' worth of "fresh tiBook" time .. a very visceral and surreal moment as I transitioned from "Ops-Center" bound, to "can hack Unix code in the park".<p>I climbed the hills of Griffith Park, and camped out at the (then-) recently burned-out hills, under what was once some old tree. I wish I'd known its species, but I'll never forget the scene; the entirety of the LA basin beneath me, as far as the Pacific, and me perched atop it. Press the button.<p>BONG!<p>I had nothing much to run on it, so I opened Terminal, fired up vi, adjusted the font to what was then an amazing degree of clarity, and wrote. For as long as the batteries held out, I set up my personal diary, pure text mode, and got it all out.<p>Still had power for a few mail-checks and touchups over the weekend, powered out on Sunday evening. The next day in LA, Monday morning, I went on the hunt for a power supply.<p>Hasn't been the same since.<p>My point? You don't need an app for that. Just vi.
