WALK THIS WAY: In the world of video games, nobody's been doing more to get us up and moving than Nintendo. One new motivator is the "Personal Trainer: Walking" game ($49.99), which works with a DS or DSi portable game system.

Clip on one of the two supplied Activity Meters (a glorified, high-tech pedometer) and start strolling. At the end of the day, point it at your DS for a second to download an accurate report of when and how many steps you've taken, with a graph and moving clock showing peaks and valleys of activity.

Your on-screen avatar offers fitness tips, comparisons to previous efforts and plenty of encouragement to pick up the pace. (FYI, while the game cheers for less, folks in the medical community suggest a daily goal of 10,000 steps, about 90 minutes of walking.)

Staycationers can still get away from it all with their Nintendo Wii system and the new "Wii Sports Resort" casual game package ($49.99, available Sunday).

Exercise your Wii remote and Nunchuck controllers to bike around an island, water ski on a beautiful blue waterway, golf on a variety of courses, master eye-hand coordination at archery, sweat it up at the ping pong table, chill in a bowling alley and more.

The game comes with that new WiiMotionPlus accessory, which wraps around the conventional remote to enhance motion sensitivity and add extra grip with its soft silicon skin. Extras sell for $20 each.

YOU CAN TAKE IT WITH YOU: On a train, riding in a car or sitting on a porch at the Jersey Shore, I've enjoyed the Internet pleasures of my portable computer.

All it took was the Verizon Mi-Fi 2200, a credit-card-sized Web access device that connects to the Verizon Wireless network and becomes a mini Wi-Fi hub with a 30-foot send/receive range.

Up to five devices (computers, iPod Touch, portable game systems) can simultaneously feed off one Mi-Fi, which I've clocked downloading at 500 kbps.

Made by Novatel (and also available in different packaging from Sprint), Verizon sells the Mi-Fi for $99.99 after a $50 rebate with a new, two-year customer agreement ($39.95 or $59.95 a month).

Or you can buy one outright for $399.99 and sign up for a 24-hour DayPass, as needed, at $15 a pop.

RADIO: Two high-tech digital radio formats are looking more attractive with new portables for your entertainment pleasure.

Just arriving at Best Buy stores is the Insignia HD Radio Portable Player ($50).
