Daydream is certainly one of the more minor features that Google added in Android 4.2
— the glorified screensavers just haven't been terribly helpful — but
with an update to Flipboard today it looks like there may be a good
reason to enable Daydream. The newest version of Flipboard adds
compatibility with Daydream, so your phone or tablet can highlight
stories from sites you follow while charging or docked. It isn't
revelatory, but it can be useful to have headlines and images pass by
while your phone is charging (new stories come in automatically if
you're connected over Wi-Fi). The update is
available now in Google Play.
