| Mobile virtual reality is the new hotness out right now—phones that users can strap into headsets and get a real, genuine VR experience are a great way to see what VR’s all about without the huge price tag. And when it comes down to it, Google nailed it with Daydream View. | |
| Modern technology has made photography a lot more accessible. In the early days, photographers had to painstakingly focus their lens by hand before they took a photo. If they missed focus, the image (and the expensive film they were using) would go to waste. Now, almost all cameras, from your smartphone to a high-end DSLR, use autofocus to make it easier to get sharp shots. | |
| Remember TV antennas? Well, they still exist. A digital TV antenna allows you to watch local TV stations for free, all without paying a dime to a cable provider. | |
| Modern PCs are ridiculously powerful, so creature comforts like low noise levels have become more important.

| The Quick Launch bar, which was removed in Windows 7, can be added back to the Taskbar in Windows 7, 8, and 10. You can also add any programs you want to the Quick Launch bar and we'll show you how. | |
| You can play the new Nintendo Switch on the TV or on the go…which means your kids can get twice as addicted to it. Here’s how to set time limits, bedtime reminders, and content restrictions on the Switch. | |
| Bluetooth headphones are the future. The iPhone 7 dumped the headphone jack and, with USB-C becoming more popular, other manufacturers are likely to follow suit. And sure, the main advantage is that they get wires out of your way—but there’s another, often unrealized, benefit in a feature called “Multipoint”. | |
| If you’ve ever noticed that your phone’s battery goes from 60% to 50% in a matter of minutes, only to remain on 50% for what seems like ages, it probably means the battery needs to be calibrated. | |
