Reddit mentions of Sony 32GB Microvault USB Flash Drive for Smartphone (USM32SA1/B)

Sony's microvault has a sleek design too: Amazon Link. Note, the micro usb is hidden under a twist cap.

Much like a Steam login, the owned game is attached to the account used, I believe; though I've not attempted to add another account to my OUYA. Will update when I test it out. As far as killer apps, here's my list of apps I can think of:

Before we start, I'd greatly advise you buy a USB Drive (32gb or 64gb). You can install games and store game ROMs and video on it. 8gb will not be enough, trust me.

Video:

• Crunchyroll streaming for Anime and Asian Drama lovers.
  
• XBMC: Media center that can play just about any audio file, video file, DVD ISO, and it also has plug-ins for YouTube, Twitch, 1Channel (for movie/TV show streaming) and a LOT more. XBMC essentially has its own ecosystem of add-ons for media. Well worth looking into IMO.
  
  • Pro tip: the version downloadable from the official website is better than the one currently posted to the OUYA store.
    
• Netflix (Unofficial): You can finds and side-load the apk for Netflix and it streams in high quality. I love it.
  
• Twitch: Self explanatory. Watch game streams. Good times.
  
  Emulators:
  
  
• Snes9X (SNES) and the ".emu" emulators (NES, Master Drive, Gameboy, etc.) are all made by the same dev. They are all free. He added a cool feature that can make the OUYA sync to a Wii Remote or Wii U Pro Controller. You can also set custom keymappings and visual styles.
  
  
• I also bought SuperGNES, which is prettier and way simpler to use, but I can't map controls with it and it has to authenticate via internet to reactivate the paid features.
  
• FPse (PlayStation 1): This one I recommend buying. It's well worth it and a great quality emulator. It has tons of features and, since you can link a PS3 controller wirelessly, it's way satisfying to play with an official controller.
  
• Mupen64 (N64): This one takes some tinkering to get it running smoothly but it's a solid emulator.
  
• PPSSPP (PSP, unofficial app): Tested it myself. It sadly can't smoothly upscale the graphics so when running smoothly it will look like a stretched PSP but it's still satisfying to play with a PS3 controller.
  
  Games:
  
  
• TowerFall Ascension: By far one of the must-haves on OUYA, this chaotic, 4-player game was the first exclusive to put OUYA on the map, games-wise.
  
• Too Many Me: This game. Is so fun. It is a great platformer with an awesome art style and fun gameplay. It's available to try before purchasing.
  
• Final Fantasy III: This game was well worth the money for me. It is a classic game that was only released in the U.S. for Nintendo DS, and smartphones at the time of OUYA's release. The OUYA was the first TV console release and it is such classic RPG fun.
  
  
• Honorable mentions go to Whispering Willows, Neverending Nightmares, Amazing Frog?, You Don't Know Jack, The Cave, DubWars, Knightmare Tower, BombSquad, and so many others I probably can't think of. These are only the games I have played. The other high-rated games in the store are pretty great too.

I use this one from Sony
