If you have a 17-inch iMac you’d like to convert to a touchscreen-based system, Apple Scientific/Technical Value Added Reseller (VAR)
can do the work for you. Troll Touch sales manager Karl Rueby recently noted that his company is offering conversions for Apple’s widescreen consumer computer.

Touchscreen systems eschew input from mice or trackpads in favor of direct contact with the computer screen itself. Troll Touch has been managing such conversions on the Macintosh since the days of the Classic — it also reworks smaller iMacs, eMacs, iBooks, and even Apple Cinema Displays into touchscreen-based systems. Such systems are useful in kiosk environments, for multimedia displays, point-of-sales terminals, educational use, and other purposes.
Troll Touch’s touchscreens use PSR-1, Pressure Sensitive Resistive technology. The company said they’ll work with any non-sharp pointer — a fingertip, for example, eraser or gloved hand. They’re not moisture-dependent, either, so they’re less likely to produce incorrect touch readings or “drift.”
The integration is handled at Troll Touch’s Valencia, Calif. headquarters, and it costs US$879. For more details, visit the Troll Touch web site.
