The Transformer Prime runs with Android 4.0 ICS (Ice Cream Sandwich), though some of the Primes on the market might still have HoneyComb installed, the updates are propagating as we speak.
For those that don't follow the Android operating system that much here is an overview:
Android 1.5 - Cupcake Cupcake was the first major overhaul of the Android OS. The Android 1.5 SDK was released in April 2009 and brought along plenty of UI changes, the biggest probably being support for widgets and folders on the homescreens. Cupcake brought features like improved Bluetooth support, camcorder functions, and new upload services like YouTube and Picasa.
Android 1.6 - Donut Released in September 2009, built on the features that came with Android 1.5, and expanded them. While not very rich in the eye-candy department, Android 1.6 made some major improvements behind the scenes, and provided the framework base for the amazing features to come. To the end user, the two biggest changes would have to be the improvements to the Android Market, and universal search. Behind the screen, Donut brought support for higher resolution touchscreens, much improved camera and gallery support.
Android 2.0/2.01/2.1 - Eclair Eclair was a major step up over its predecessors. Introduced in late 2009, Android 2.0 first appeared on the Motorola Droid, bringing improvements in the browser, Google Maps, and a new user interface. Google Maps Navigation was also born in Android 2.0, quickly bringing the platform on par with other stand-alone GPS navigation systems. Android 2.0 quickly gave way to 2.0.1, which the Droid received in December 2009, mainly bringing bugfixes. And to date, the Droid remains the phone to have as it explicitly received Android 2.0.1.
Android 2.2 - Froyo Android 2.2 was announced in May 2010. The single largest change was the introduction of the Just-In-Time Compiler -- or JIT -- which significantly speeds up the phone's processing power. Along with the JIT, Android 2.2 also brings support for Adobe Flash 10.1. That means you can play your favorite Flash-based games in Android's web browser. Froyo brought native support for tethering, meaning you could use your Android smartphone's data connection to provide Internet (wirelessly or with a USB cable) to just about any device you want.
Android 2.3-2.4 - Gingerbread Android 2.3 came out in December 2010, Gingerbread brings a few UI enhancements to Android, things like a more consistent feel across menus and dialogs, and a new black notification bar, but still looks and feels like the Android we're used to, with the addition of a slew of new language support. Gingerbread brings support for new technology as well. NFC (Near Field Communication) is now supported, and SIP (Internet calling) support is now native on Android. Further optimizations for better battery life round out a nice upgrade. Android 2.4 is also in the Gingerbread family.
Android 3.X - Honeycomb Android 3.0 came out in February 2011. It's the first version of Android specifically made for tablets, and brings a lot of new UI elements to the table. Things like a new System bar at the bottom of the screen to replace the Status bar we see on phones, and a new recent applications button are a great addition for the screen real estate offered by Android tablets. Some of the standard Google applications have also been updated for use with Honeycomb, including the Gmail app and the Talk app. Both make great use of fragments, and the Talk app has video chat and calling support built in. Under the hood, 3D rendering and hardware acceleration have been greatly improved.
Andoid 4.x - Ice Cream Sandwich The follow-up to Honeycomb has been announced at Google IO in May 2011. Dubbed Ice Cream Sandwich, Google declined to give the version number but said it would bring elements of Honeycomb tablets to smaller-screened smartphones.
So back to the Prime, you can understand why we really like ICS, Honeycomb has been both hated and loved on Tablet -- ICS feels really good in combo with Tegra 3. During our review we got notified of yet another ICS update, the device is now running Andoid 4.0.3
If you haven't done so, on the first page we show you a video covering the look and feel of Ice Cream Sandwich on the Transformer Prime. Check it out if you skipped it.
ASUS Transformer Prime Review Ever since the first Android tablets arrived a year or two ago things have been developing fast. ODMs and chip designers jumped onto the bandwagon fast as PC sales are declining, and much like the initial netbook market, the tablet market is on the rise. We test the The quad-core Tegra 3 based Eee Pad Transformer Prime, an unbelievable product. Fast, thin and huge in specs, but sure... very expensive.
