Baca comment2 di artikel webnya seru juga tuh Dan Andrew Munn <https://plus.google.com/100838276097451809262/)> sendiri justru sebel tulisannya dikutip Apple blog Google+ : https://plus.google.com/100838276097451809262/
"One thing that upsets me is that Apple blogs are using my post as evidence that Android will never, ever be as smooth as iOS. I don't think this is necessarily true. It may not be at the moment, but look at all the progress that's been made between Android 1.5 and 4.0 in a few short years." Tapi memang iOS device lebih smooth sih :) On Wed, Dec 7, 2011 at 8:59 AM, A.W.
