Top vendors like Google, Apple hope to take smartwatches mainstream in 2014

Smartwatch developers must focus on cutting prices, adding more apps, and improving the look to attract broad consumer interest

When International CES opens in Las Vegas in early January, a flood of wearable computing devices, including smartwatches, will be on display.

The fledgling smartwatch market is tiny compared to that for smartphones, or even wearable devices like Google Glass or smart

Still, the smartwatch phenomenon promises to blossom in 2014 as experts expect Google to launch a model by summer followed by Apple sometime in the fall. Even Microsoft is reportedly working on one.

To achieve any degree of greatness, though, these major tech innovators and their smaller competitors must overcome some significant hurdles.

For instance, most of the smartwatches unveiled to date are too expensive, at $200 to $300 each, for widespread adoption. Most of the devices also require a connection to a smartphone via Bluetooth, which implies that users face the added cost of the smartphone and a wireless service contract.

The early smartwatches also lack functionality and mostly run fewer than 20 smartwatch apps.

Southampton University supercomputer goes live

A £3.2m supercomputer, one of the most powerful in the UK, has been installed at the University of Southampton.

The Iridis4 has 12,200 processors, each of which can perform a trillion calculations per second - a measurement referred to as a "teraflop".

The IBM machine also has a million gigabytes of disk space and 50 terabytes of memory.

Home computers generally have between 500GB and 2TB of disc space and about 4GB to 6GB of memory.

There are 1,024 gigabytes in a terabyte.

The university said the new machine would allow academics to work on more projects at faster speeds.

The world's most powerful computer is China's Tianhe-2, which can perform 33,860 trillion calculations per second.
