Alexa lets you make calls, send messages from your tablet - CNET. Alexa is a handy addition to my bedroom. Get your mind out of the gutter. I am talking about my Voice Assistant. When I wake up in the middle of the night to do what all old men do, it is nice to be able to ask Alexa what time it is. However, at 2:30 in the morning, I don't always appreciate her kind voice. I also can get a daily news, weather and sports briefing that is full of handy information. Now, I can make phone calls by voice activation, and soon I will be able to use Alexa from a tablet computer. Anybody out there brave enough to take a video call from me at 2:30 in the morning? Didn't think so. Go back to sleep.
