Here are some more thoughts: I love how Google Play Music will read the music I have on my external SD card. I have a 32 Gig card and so have music on it 'cause my OM+ only had about 2Gig of internal memory. The OM+ wouldn't read music from the SD card though, so I always had to stream. Fortunately we had decent 3G here in the Dallas area so I could do that. Well, no sooner did I pop my SD card into the Motion, turn it on, and I checked Play Music and selected on device music. Sure enough, there was my music. I'm really happy about that. I was using Amazon MP3 to play my music from the external SD, but now I have even more options. I like options.
I'm also loving the stock backup app. On my OM+ (and OM before that) I was rooted and so used Titanium Backup and I also used CWM to make backups. I understand, and know that root and CWM is available for the Motion, but I haven't rooted yet. Really, I'm not even sure if I will at this moment. I'm quite content and happy playing with the phone as stock right now. Maybe down the road. We'll see.
Thanks for listening.
