I for one have not bought into Google's, or anybody else's, idea that streaming everything is so great.  With all the regressive data caps and sketchy throughput, I never want to rely on something being available to me online.  Much better to have it local.  And with this new card I can finally pack all of my music (~56GB), all of my photos, dozens of reference ebooks, and a few videos to boot and still I have around 9GB free as breathing room for my podcatcher.  The only real bummer with this card is the speed.  Just as I got acclimated to SanDisk's 64GB Extreme Plus level of speed, going back to ordinary class 10 speed that this card has is a little painful.  Luckily playing music or even playing videos doesn't oversaturate the read performance.  What WILL trip you up however is doing a straightforward copy or move operation while you're listening to something.  This card does not seem to handle multiple simultaneous operations without something going awry.  So long as you understand it's limitations and you can live with them, the enormous amount of storage you can pack into your phone or tablet is very welcome.So far I've used one of these in a Samsung Galaxy Note 2 N7100, LG G Pad, and a Sony Xperia Z1 Compact - all with success.
