John Dvorak had an interesting piece recently on the transformation of computers “from being a mathematical tool used for calculations, to a communications device.”

Initially, computers were used for calculations. The first intended purpose was for artillery trajectory calculations — hardly a noble purpose, but certainly a practical one. In the early days, computers were described as electronic bins. … As the desktop computer revolution developed, the devices’ uses were inevitably based on some aspect of calculation. Spreadsheets were the perfect example. At the time, the only communication aspect of computers was the fact that they could double as powerful aids to word processing software.

By 1979, however, modems and networks were making inroads. They made it possible for computers to talk to each other in some crude way. That was the beginning of the end. The computation aspect of computers continued to grow, but it was the networking aspect that was the disease vector, so far as social upheaval is concerned. You can figure out the rest of the networking timeline. It began 30 or more years ago — 40 years, if you want to count the invention of Arpanet in 1969.

The iPad and smart phones are just the logical conclusion to this trend: computers whose only real purpose is to communicate, not calculate.

Whatever the grand social implications of “the communications-oriented computer” — Dvorak considers it an asocial, porn-proliferating, newspaper-killing “disease” — it has been a disaster for writers, at least for this highly distractible writer.

I’m no Luddite. I love the web, maybe too much. Most evenings now, after my kids go to bed, I find myself opening up a laptop and reading online when once I would have opened a book or turned on the TV. To a natural reader, it is like heaven — an endless library. (Also an endless TV and jukebox, but personally these aspects interest me less.)

That is just the problem: the web is a massive distraction that is becoming increasingly difficult to tune out. Today you can’t buy a new laptop that is not wifi-enabled, and you can’t walk into a library or Starbucks that does not provide wifi. No doubt computers eventually will follow smart phones into a world where all computers are connected to the web all the time, with or without wifi.

The irony is that today’s computers are actually less useful for writers than were the slower, “dumber,” un-networked boxes of ten years ago. That is because writers need to do the one thing modern computers can’t — disconnect.

I hear the objection already. “Why don’t you just turn off the damn internet for a while? Close your browser. Show some willpower, some discipline!”

Well, that is what most writers do. What choice is there? But over and over I hear writers echo my own experience, which is that the web is very difficult to block out entirely, because the same machine we use for typing is also the one we use for web-surfing. Our work tool has become a play tool. Our typewriter has become a TV. What you scolds may not understand is that our work is different from yours. Writing of any quality requires deep focus; long, quiet, undisturbed stretches of time; and isolation — in Joyce’s famous phrase, “silence, exile, and cunning.” Any work that involves serious thought requires some of these things some of the time, I suppose, but good writing needs them all, every day. And modern computers, alas, are designed to create the opposite environment: distraction, connection, zoning out.

What we writers need is a computer optimized for word processing and nothing else. A “dumb” computer that is little more than a “smart” typewriter. A workspace — a computer screen — with no distractions, that does not tempt us to pop online “just for a minute to check email.”

I have found something close in the AlphaSmart Neo, a simple plain-text word processor with virtually endless battery life, whose praises I have sung before. But once I have completed a draft of a novel and moved to the editing phase, I have to use a word processing program, in my case WordPerfect, to which I am passionately, stubbornly devoted. That means I have to switch to a laptop.

So how do I work on a laptop and completely shut out the web? By eliminating all the “advances” of the last decade.

I recently bought an old ThinkPad T23 on eBay. The laptop was made in 2001 or thereabouts. It was a high-end machine at the time, with a retail price well north of $3,000, but I picked mine up for about a hundred bucks. The build quality of these old ThinkPads is unsurpassed, and the T23 is engineered to be light and tough enough for corporate road-warrior types. It has a great keyboard but, honestly, not much else. Best of all, it has no wireless card.

A nine-year-old laptop is not a perfect solution, of course. Battery life is short (I get about 1:45). At 5.5 pounds the T23 weighs a little more than today’s ultraportables. And with such an old machine, who can say how much tread is left on the tires? But so far I am thrilled. To a writer, less is more. I bought this computer precisely for what it can’t do.

I wonder: isn’t there enough of a niche market to support a new laptop like this, which sacrifices processing power, memory, and networking ability for the simpler things that writers and other thinkers value — low price, long battery life, light weight, good keyboard, bright screen? The ideal writer’s computer would have many of the virtues of a netbook, minus the connectivity, plus a little size to accommodate a better keyboard and display. It would be good for students, too. Certainly it would be a machine John Dvorak would love.
