Which cell phone to choose? What software to buy? Are camera-binoculars a necessity or novelty? As release cycles shorten and ever-shrinking gadgets hit the market with dizzying speed, it's harder and harder to know what's worth the investment.

After happily weathering installation nightmares, customer service hiccups, and an overwhelming crush of backups, upgrades and downloads, Pogue reports back with his recommendations via his many columns, TV appearances and how-to books. And he does it all with relatable insight, humor and an unsinkable sense of pun, er, fun. All that, and he sings, too.
