My third-party wireless speakers never heard about DNLA but they support rock-solid AirPlay.
I didn't talk about controllers (the posting that I replied was about "advanced"and not commonfeatures) but about bluetooth synced games between multiple devices (Real Racing 2, Asphalt 6: Adrenaline, Sega & Sonic Racing
). P.e. Asphalt 6 exists for Android but doesn't support bluetooth local multiplayer which is an exciting new racing feeling. Let alone retina resolution w. super smooth 60 fps on iPad 3 p.e.
As for common features like game controllers we have iCade (nothing like this for Android) and iControlPad and that's all you need.
An independent German mag for sound engineers choosed iOS devices as the best mobile sound quality products. "Best MP3 player.""Best value sound production tool of ALL software/OS platforms." (Even better value than Macs.) That means: If you want to dig in electronic sound production you get most for you money with iOS hard- and software.
OpenFeint was developed for iOS devices in the first place, I had it since day one but it became awefully slow, sluggish and finally stopped working (login okay but doesn't count my scores any more). Game Center is much better and reliable. OF doesn't even support online multiplayer gaming.
You MAYBE will find ONE Android OS update during the lifetime of your Android device if you're lucky enough. No matter if Over The Air or wired.
No thanks. I'll decide if and when I want to update an app.
So please educate yourself what I mean with professional audio production. Android is not even a TOY when you compare those features.
Have a quick look at the recent postings in MR's sister site touchArcade's forum thread "Apps For iOS Musicians" with the advanced synths and beat machines by Propellerheads (Roland Emulators), Native Instruments, Korg, Moog and all the other most famous names of that genre (no toys, highly professional):

Try that with Android (VirtualMIDI Madness in Genome w/ Sunrizer, Bassline, Molten & MoDrum):

You can even connect external MIDI devices. Wireless or wired. Have a look at sophisticated peripherals like
Alesis iO Dock Pro with XLR plugs. Or iRig for guitarists (tuner, pedalboard, amp head, cabinet, microphone AND 4 track recorder) and iRig MIX/DJRig for DJs (portable iOS DJ mixer, you can plug in and cue ANY source audio, and X-Sync will automatically match the tempo and make your transitions seamless. You can use ANY of your audio sources in your mix like a second iOS device, cd players, other MP3 players, whatever). It just works.
When I talk about advanced OS features then I don't mean OTA updates. Android/Google has still to learn a lot besides hardware, design, respecting privacy and NEVER spying user data (very bad reputation). It's not even worth to be called plagiarism. Wannabe plagiarism with data collecting mania maybe
