Free group messaging. It's like a private chat room for your small group. Have as many as you want, and it's always free. Now, you can coordinate with coworkers, organize a game night, and keep in touch with family all in the same place.
Contrary to what you might think (or have been told), leaving your phone or laptop plugged in all the time is not bad for its battery. That's because your gadgets, the batteries in them, and the chargers you attach them to are actually pretty smart about the way they do business.
When I called SquareTrade and asked them if they would cover the 13 phones I just bought for my company they said that they do not cover company's phones -- only ones for personal use. I would think that covering a company's phones would be more lucrative since there is a low likelyhood that all of these phones will break. Too bad SquareTrade is limiting coverage to only personally purchased phones. They are missing out on a large opportunity.
