I'm really amused by all of the Apple people who are "ripping Nest off the wall" since it was announced that Google bought the company.
Their reasoning? They don't like that Google will be able to determine when you leave home. I'm pretty sure that Google does not have a army of house burglers waiting to for you to leave your house.
The next item is that Google will just shut it down in a year. I don't see that happening either, if anything they'll improve on it. You don't spend $3.2B on a product and then shut it down.
