iPhone Duo Review: The Hardware Is Ready, the Apps Aren't

I bought a night sky iPhone Duo with 1TB on launch day, coming from an iPhone 17 Pro Max. The hinge has been smooth, the cameras are a step back, apps are uneven, and I haven't been this excited about an iPhone in years.

iPhone Duo or iPhone 18 Pro Max? What $700 More Buys

The iPhone Duo costs $700 more than the iPhone 18 Pro Max at every storage size: $1,999 against $1,299 with 256GB. The extra money buys a 7.6-inch screen that folds to about the size of a passport, with Apple Pencil support due later this year. It gives up the telephoto camera, Face ID and about four hours on Tom's Guide's battery test. Specs, same-lab battery tests, cameras, repair costs and who should buy which.

iPhone Duo Repair Cost: Is AppleCare+ Worth It?

Out of warranty, Apple charges $999 to fix the iPhone Duo's folding inner screen and $379 for the outer one. AppleCare+ with Theft and Loss costs $199.99 a year and cuts those fees to $99 and $29, so one inner-screen repair is worth four and a half years of the plan. Every repair price, the break-even, AppleCare One, and how Verizon, AT&T and T-Mobile compare.

Kids Are Getting Felonies Over a Cat in the Hat Meme

The creepy AI Cat in the Hat stalking driveways on TikTok has never been found in real life. The kids who post him with a school's name attached are being found fast. At least 15 minors in 10 states have been arrested or face charges in two weeks, several with felonies, under school-threat laws written after real shootings that do not care whether it was a joke.

Tesla Extended Warranty: Is the Monthly Plan Worth It?

Tesla's US Extended Service Agreement costs $50 a month on a Model 3, $60 on a Model Y, $125 on a Model S and $150 on a Model X, before tax, plus a $100 deductible per repair visit ($200 on some older Model S and Model X). It starts when the 4-year or 50,000-mile basic warranty ends and can run up to 4 more years or 50,000 more miles, but never past 8 years or 100,000 miles on the car, so at the July 2026 price the most a Model Y owner pays in fees is $2,880. It excludes the battery and drive unit, which every Tesla factory warranty edition read for this page, back to 2017, covers at least that long. It pays off only if covered repairs cost more than the fees plus deductibles, and a car whose plan is cancelled can't be enrolled again.

Which Tesla Model 3 Should You Buy? Each Trim Compared

In October 2026 Tesla sold four versions of the Model 3 in the US, from the $36,990 rear-wheel drive to the $54,990 Performance. The $5,500 step to the Premium rear-wheel drive buys 42 more miles of EPA range, ventilated front seats, heated rear seats and a rear touchscreen. Here is what every trim costs, how far it goes and who it suits.

In October 2026 Tesla sold six versions of the Model Y in the US, from the $39,990 Model Y rear-wheel drive to the $61,990 six-seat Model Y L. The $6,000 step to the Premium buys 36 more miles of EPA range, a glass roof, heated rear seats and 15 speakers. Here is what every trim costs, how far it goes and who it suits.

Why Your Electric Bill Spikes in Winter, and How to Cut It

The average US home paid about $133 for electricity in October 2025 and about $175 in January 2026, by a calculation from EIA utility data, and the price per kilowatt-hour fell in most states over those months. On average the jump is usage, not price: homes that heat with electricity, space heaters and longer nights of lighting, with the furnace's blower fan and electric water heaters as other winter loads. EIA's October 2026 forecast has homes that heat with electricity paying about 4% more this winter than last. Here are the state numbers, the forecast by region, what the common plug-in culprits cost a month, and the cheap ways to stay warm: blankets and layers, heating only the rooms you use, thermostat setbacks, finding drafts with a borrowed thermal camera and sealing them, wood heat done safely, frozen-pipe prevention, and help paying the bill.

Trump Picked Warsh to Cut Rates. Warsh Raised Them Instead

The Federal Reserve raised its benchmark rate a quarter point on September 16 to a range of 3.75% to 4%, its first increase since 2023, in a unanimous vote under the chair Trump chose to bring rates down. Credit cards and home equity lines reprice within a billing cycle. The Fed did it with core CPI at its lowest since 2021, and its own forecast pencils in one more hike this year.

Which Meta Glasses Should You Buy? Ray-Ban, Oakley, Display

For most people, Ray-Ban Meta (Gen 3) at $449 is the pair to buy. Gen 2 at $379 saves $70 for an hour less battery. The camera-free Ray-Ban Meta Audio costs $349, the $249 Meta Adventurer is the cheapest new current-generation pair, the $499 Oakley Meta Vanguard is for hard training, and the $799 Meta Ray-Ban Display is the only one with a screen. Check the prescription limits before you buy, because they differ by model.

Which AirPods Should You Buy? Every Model Compared

Apple sells four AirPods in October 2026. The $129 AirPods 5 suit most people and now cancel noise. Pay $149 for the Wireless Charging Case if you want volume swipes and an extra hour per charge. The $249 AirPods Pro 3 add stronger noise cancelling, ear tips, heart rate and Apple's hearing aid feature. The $549 AirPods Max 2 are the over-ear choice. Live Translation needs an iPhone 15 Pro or newer.

Do MagSafe Accessories Work With the iPhone Duo?

Yes for charging: the iPhone Duo takes MagSafe and Qi2 chargers at up to 25W. Fit is the catch. Upright stands can tip when the Duo is open, and none of the chargers and power banks this site picks lists the Duo, nor does Apple's own MagSafe wallet. What works folded, what works open, and which accessories name the Duo.
