I've had the Shield for years and set them up for a few family members. I still believe it's the best device of its kind on the market and I've recommended it every chance so I have a lot of friends with them as well.

In the most recent update, the until-now ad-free homepage was defaced with an ad banner that takes up half the screen and can't be removed. This wasn't a change made by Nvidia but by Google to the Android TV Launcher. To add to this, some of the ads have been deemed inappropriate or offensive to certain users adding to the frustration of ads being introduced to this long-standing ad-free experience.

I, like many Shield owners, am considering installing a third party launcher. This can be done pretty easily by watching an instruction video on Youtube and most users will go this route without consideration of security - potentially opening large numbers of the devices up to vulnerabilities.
