As expected (CI No 2,991), Toshiba America Information Systems Inc jumped into the desktop fray yesterday with a line of home PCs called Infinia available from CompUSA and Best Buy stores. Toshiba still won’t say who’s building them but the three models use Pentium 133MHz, 166MHz and 200MHz processors cost from $1,700 to $2,800. The Toshiba LCD or LED monitors ship with Toshiba’s InTouch Module and remote control, which allows users to tune to radio and television stations, make phone calls, check for phone messages and play compact disks. But aside from the multimedia aspects, how will Toshiba differentiate itself in the marketplace? By offering midnight gray machines with sleekly styled silver accents that add style to any room, of course. But that design seems a bit too reminiscent of Sony’s sleekly styled violet and gray PCs launched in June for about the same price (CI No 2,936). We’re still waiting for pink PCs for the Barbie and My Little Pony set.
