iPhone Life - Best Apps, Top Tips, Great Gear

Before the recently enhanced Apple TV was introduced, rumor sites speculated that Apple might actually make large-screen television sets and embed its Apple TV intelligence into them. I was never a fan of that strategy. TV sets are fragile and bulky, and Apple doesn't need to get into that business. For several years, I have relied on an Epson projector connected to an Apple TV for my home entertainment. I've never looked back since I set up the home theater system. My screen is as large as my wall, which is far bigger than any TV set at Best Buy. I mounted the Epson projector to my wall and painted the screen-side of the wall with a special paint to make the image even better.

Walmart hasn't adopted Apple Pay, and it's not clear whether it will (though one report I read said the company is increasingly open to it). Now, however, you have another option for paying at Walmart. Last week the company launched a new mobile payment system at selected stores that lets you pay for your purchase at the checkout counter by scanning a QR code with your iPhone or iPad. (For it to work on an iPad, though, you'll likely need to have a cellular data model.) The new mobile payment system will be available nationwide by the first half of next year.
