There is a high probability that Google will launch a Pixel tablet. As they will probably want to expand their Pixel device range. I doubt it as the first Pixel devices launched were selling at premium prices. The best thing to do is keep your mobile devices on your person or stored securely in your bag. I don't understand why people leave them lying about in public places. You might as well put up a huge neon arrow sign that says "Free Phone Come & Get IT"
