TOKYO - Even if you don't like video games, you'd best resign yourself to what appears certain to anyone who's spent a little time with Sony's new PlayStation Portable:

This is a gadget that's likely to eventually become a worldwide household hit. That holds true especially if your household includes, as mine does, a young man who grew up with the original PlayStation.

Yet, while the PSP is a dazzling game machine, delivering sharp graphics on a 4.3-inch display and weighing just 10 ounces, it is also a multimedia player designed for music and movies.

And within the sleek, black plastic shell of this 7-inch-by-3-inch wonder, there is Wi-Fi wireless connectivity and a USB 2.0 port for mating with computers.

The big drawback is Sony's decision to go with a proprietary format for the PSP's main media: a 1.8-gigabyte disc the size of an Olympic medal. It's dubbed UMD for Universal Media Disc.

That's what the games come on - and Sony promises to also deliver Hollywood movies on the discs, though it hasn't said when or offered a lineup.

The PSP went on sale in Japan this month but won't be available in the United States until next year. It's likely that the U.S. price will be similar to the $190 the device costs in Japan. That feels like a bargain to anyone who remembers paying more than $299 for the original PlayStation in the mid-1990s.

But then, the PSP has a competitor this time around in Nintendo's DS handheld. Perhaps that's why the PSP is stoked with enough technology to be worth twice its price tag - it's got a Memory Stick slot for storing music and photos when the 32 megabytes of onboard memory don't suffice. You'll have to buy the Memory Stick, though.

Also, the PSP is an MP3 adherent, and its sound quality is quite good.

If you want to play video that doesn't come on a UMD disc, Sony recommends you buy special $10 computer software that will convert it to the MPEG-4 video format that the PSP and Memory Stick support.

PSP games range in price from $24 to $46, but there aren't many yet.

Sony says some 100 games are in the works, with about 20 titles promised soon.

In the games I played on the PSP, the attention to detail in the graphics was impressive.

The display, from Sharp Corp., is surprisingly easy on the eyes. The removable Lithium Ion battery lasts about four to six hours for games on a single charge. And the built-in 802.11b Wi-Fi chip allows up to 16 PSPs to play together.
