With any new technology it always takes a little while to figure out exactly how it should work. Remember the crappy touchscreen phones that required a stylus before the iPhone came along? Or how motion controls were only ever used for stupid party-game collection before the... hmm... no, sorry. Er, ignore that.
Anyway - the next big technological unknown looks set to be smartwatches. The tech is just about mature enough to mean that you won't be carrying around a refrigerator on your wrist, and we're currently watching as the big tech companies experiment to find the way to make a smartwatch a must-have device. Here's ten of the leading competitors at the moment.
Perhaps the most accomplished smartwatch yet, the Sony SW2 links up to your Android phone via bluetooth (and can connect via NFC meaning no fiddling with passcodes). Sony reckon the battery will last for 3-4 days of normal usage, and built in functionality includes call handling, text message notifications, email and Gmail notifications, as well as controls for your music playing on your phone. It can even check your Facebook and Twitter on the go, or show your photos in a slideshow. It looks perhaps the slickest of all of the smartwatches so far too - nice!
