NY Times:
"By far the most important change, however, is smoothness. Google engineers knocked themselves out trying to make Android 4.1 as responsive to your touch as, ahem, the other leading tablet. Animations all run at a supersmooth speed of 60 frames a second. Google says it tries to anticipate where your next finger touch will be, and begins to redraw the screen at that point.
Wow, does it work. Google’s tablet is now Applesque in its fluid touch response. All other makers of touch-screen gadgets should take note."
Gizmodo Australia:
"When you actually get down to using it, the new version of Android known as Jelly Bean, rewards you with super-fast performance coupled with smooth operation. Google tweaked a lot of things between Ice Cream Sandiwch and Jelly Bean — right down to new window animations — and that care really shows."
Techradar:
"Swiping through screens is fast and responsive – even on apps that haven't yet been updated for 4.1 – while flipping through one of the visually rich magazines now available from Google Play doesn't miss a beat. Ridiculous name aside, Project Butter delivers the goods."
PC World Australia:
"The main feature of Android Jelly Bean is what Google calls "Project Butter", which centres around making the software smoother, faster and fluid. The company claims using Jelly Bean feels a lot smoother than previous versions of the platform and we have to agree. This is by far the best version of Android yet. Using it on a day-to-day basis is smooth, intuitive and fast. There is no sign of any evident lag during everyday tasks. Home screens are butter smooth to swipe through, even with multiple widgets on the screens. Apps open quickly, with no delay. The default browser, Google Chrome, is fast, renders pages efficiently and offers good performance."
