If you plan on giving or receiving gadgets this holiday season, one Stamford tech expert recommends doing some research beforehand.

Bud Freund says he teaches people - from grade-schoolers to senior citizens - how to make technology do what it's supposed to do, and avoid what it's supposed to avoid.

Freund says some of the hottest tech gifts this year are once again tablets and smartphones, due in part to their convenience and portability. A cheap accessory such as a Bluetooth keyboard can turn these devices into equal parts tool and toy.

For those who travel often, Freund offers some battery-saving tips for smart devices. He says to turn off Wi-Fi and other features to stretch that battery as long as possible.

Freund will be presenting a technology workshop next month at the Rowayton Library.
