Is your home office lacking some gadgets? Maybe your computer blew a chip and Web withdrawal is taking its toll? Perhaps you've never had a computer and want to see what all the fuss is about? Internet access is not only available at Kafka's, it's cool. Long a ramshackle used bookstore and coffee bar with a European beatnik feel, the place has added about twenty Pentium II and III Hewlett-Packard computers. Amid the books and magazines are a color laser printer, scanners, equipment to duplicate CDs, and even the stuff you need to video-conference. Translation programs for French, German, Spanish, English, and Italian also are available. Open from 9:00 a.m. to 11:00 p.m., this is a low-budget nerd's dream. The first hour of surfing costs nine dollars, and then the price drops on a sliding scale. You have to pay but a buck to log on for the minimum. To maximize your typing speed, you might want to get jacked on some strong espresso before beginning. If it's all too 21st century for you, read a book.
