Not the poster's fault, but the original title is ignorant at best and deliberately deceptive at worst.<p>First, Samsung did <i>exactly</i> what Google suggested to Cornerstone / CyanogenMod - make it an optional extension that apps can opt into. Here's some (unofficial) documentation about that: <a href="http://www.modaco.com/page/news/_/android/developers-add-support-for-samsung-multi-window-to-your-apps-r823" rel="nofollow">http://www.modaco.com/page/news/_/android/developers-add-sup...</a><p>Second, I have a Galaxy Note 2. Applications that support multi-window on my phone (i.e. where the application developer has opted into the feature) include: Gmail, Chrome, (Google) Maps, YouTube and (Google) talk. I'm sure all of that was done over the vociferous objections of Dianne Hackborn and the rest of the Android team.
