I'll rage. Seriously. It won't import in with my Google (Gmail) account?
I also don't want to have to re-purchase all of my Android/Play store apps again (I have a now 2 year old Droid X).
I'm fairly certain you will have to do this
Nope, Google says I don't have to repurchase these apps: http://support.google.com/googleplay/bi ... wer=113410
The sweet thing about my wife's iPhone and iPad is that we use the same iTunes account for both, and when I get an app for the iPad, it syncs to her iPhone. Like Minecraft PE, it cost $6.99, but we can install and use it on the two devices. I assumed that would be the case for Android.
As for movies, yeah, you can rent movies via the Play store. We rented Elf on the way to Canada last year, and the kids watched it on the road via 3G. With the streaming movie, streaming music (Pandora, Google Play Music) and the 14 hour drive to Toronto, it was the only time I ever came close to going over my "soft cap" of 2 GBs of data. Although I am/we are unlimited right now, this will switch to 1GB when I re-up my contract with the new phone.
Edit: Someone in the Droid thread mentioned that the S3 actually has two micro SD slots, so technically I could plop the SD card from my Droid X and pull over the pictures that way...
