Acer is the latest company to join the 'phablet' race with its new Liquid S1 device unveiled at Computex 2013.

The new Acer Liquid S1 sports a whopping 5.7-inch HD display with a resolution of 1,280 x 720 pixels at 257 pixels per inch (ppi), keeping up with the trend of increasingly bigger smartphone displays. Samsung is the notorious pioneer when it comes to pushing the limits in terms of size, but Acer's new phablet looks set to take on the 5.5-inch Samsung Galaxy Note 2 and it even has an optional digital pen to match the Note's experience. The Galaxy Note was the first device to merge the phone and table experience into a "phablet."

The new Acer phablet packs a quad-core processor clocked at 1.5GHz, 1GB of RAM and runs on the very latest Android 4.2 Jelly Bean mobile operating system. The device also includes a dual-SIM option, which is just one of the features due to which Acer claims the Liquid S1 is an all-in-one mobile device.

When it comes to the business side of things, the Acer Liquid S1 promises to cater to users' needs, allowing them to wirelessly and retrieve files in a simple manner via AcerCloud Docs. Users will also be able to enjoy Acer Remote Files, which comes particularly in hady for remotely accessing files from a main PC. The phablet also allows business users to project their presentations in 720p HD or print documents via wireless display and print features, respectively.

"The Liquid S1 combines the work efficiency of a tablet PC with the convenience and multimedia-rich features of a smartphone," boasts the press release, as published by Engadget. "It is an all-in-one mobile device that opens up more possibilities for users to communicate and explore."

Apparently Acer had a hard time deciding between a smartphone and a tablet, so the company essentially made with the Liquid S1. Users can enjoy the smartphone side while on a call, while also using the device's other features such as a calendar for multi-tasking via an overlay "float application."

The "Acer Float" User Interface allows users to have several app windows open. This means multitasking will no longer require quitting an app to work on another. Users can bring up the Float Apps shortcut simply by pressing a key. Holding the options key down for a few seconds, for instance, will bring up a popular or most used "Float Apps," conveniently displayed as shortcuts on a translucent screen. These shortcuts include camera, maps, calculator and notes and will float over whatever function is in use at the time.

In terms of cameras, the Acer Liquid S1 has both front- and rear-facing shooters. The front camera boasts 88-degree viewing angles with a 24mm wide angle lens which, according to Acer, is ideal for video conferencing. The rear camera, meanwhile, has an 8-megapixel sensor with a 28mm lens, LED flash and support for HD 1080p video recording.

Acer Liquid S1 phablet is headed to Asia and Europe, with no hints currently indicating a U.S. release. It will launch in the third quarter across France, Belgium, the Netherlands, Ukraine, Russia, the UK and Germany, sporting a €329 price tag, i.e. about $427.
