ASUS PadFone
ASUS PadFone was unveiled at Mobile World Congress in February

ASUS unveiled its revolutionary PadFone at this year's Mobile World Congress (MWC) event. The device is reportedly a three-in-one - combining a smartphone, a tablet and a notebook - when paired with a PadFone Station or PadFone Station Dock. The device comes with the PadFone Stylus Headset and a Bluetooth Stylus Pen and is expected to hit most European markets in May.

Meanwhile, the expected announcement of the Samsung Galaxy S3 is only a few hours away and while there is little official information on its specs, there are several rumours to draw on.

Check out how the two stack up

Display: The Samsung Galaxy S3 is likely to feature a 4.8in Super AMOLED display. A photograph of what is claimed to be a Samsung Galaxy S3 was found online recently, which also suggested a physical "Home" button and a five column User Interface (UI). The PadFone features a 4.3in Super AMOLED capacitive touchscreen, with a resolution of 540x960 pixels. The display is protected by scratch-resistant Corning Gorilla Glass with HCLR Film.

Dimensions: An earlier IBTimes UK report suggests the Galaxy S3 will be thinner and slightly heavier than the S2. ASUS' PadFone measures 128x65.4x9.2mm and weighs 129g with the battery.

Operating System: Both devices will run on Android 4.0 (Ice Cream Sandwich).

Processor: Samsung has confirmed its next Galaxy device will be powered by a 1.4 GHz Exynos 4 quad-core processor. The Exynos 4 quad-core has twice the processing capabilities of the 45nm process based Exynos 4 Dual and the processor consumes 20 per cent less power. The US variant of the Galaxy S3 could pack Qualcomm's dual-core Snapdragon S4 processor. However, a leaked service manual states the Galaxy S3 will be powered by a 1.5GHz quad-core CPU. Either way, the Galaxy S3 will house 1GB of RAM.

The PadFone is powered by Qualcomm's Snapdragon S4 8260A dual-core processor, which was clocked at 1.5GHz and the device has 1GB of RAM.

Camera: The Galaxy S3 is expected to have an eight megapixel front-facing camera with auto-focus and LED flash. It should be able to capture videos at 1080p. ASUS' PadFone also sports an eight megapixel camera and a 0.3 megapixel front-facing unit.

Connectivity: The Galaxy S3 will offer Wi-Fi 802.11 b/g/n and Bluetooth version 4.0 and it will also support data speed up to HSPA+21Mbps and HSUPA 5.76Mbps. The ASUS PadFone supports WLAN 802.11 b/g/n and Bluetooth version 4.0.

Storage: The Samsung Galaxy S3 will offer 16GB of onboard memory; the PadFone has two models - 16/32GB. Both devices support microSD cards.

Battery: The Galaxy S3 is expected to carry a 2050mAh battery. The ASUS PadFone is powered by a 1520mAh Li-ion battery.
