TOKYO (AP) – It may not be a cause for alarm just yet. But computer makers just might want to take note of what’s happening in Japan these days. The personal computer market in Japan is starting to shrink. So much so that some analysts are wondering if Japan will become the first major market to see a decline in personal computer use. And if that does come to pass, it remains to be seen whether it will be the start of a trend that will spread elsewhere in the world. An official with the market survey firm IDC says this may be more of a trend than a blip. He says the home PC market is losing ground to things like flat-panel TV’s, mobile phones and other hand-held gadgets. He notes consumers aren’t as impressed as they used to be with bigger hard drives or faster processors for their computers. What’s more, he notes, many Japanese kids are growing up using mobile phones to communicate, not PCs.
