The first and, most interesting, is the Vaio Tap 11, a slimline Windows 8 tablet with a detachable battery-powered keyboard.
Then there's the Vaio Fit, three multi-flip laptops of various sizes. Finally, there's also a larger, aluminium version of the earlier Vaio Tap 20, called the Vaio Tap 21.
Vaio Tap 11
The Windows 8-toting Vaio Tap 11 is clearly designed to smash Microsoft's Surface Pro into the ground and even features its trademark kickstand. We can't wait to see this one - it has a Full HD display and an active stylus. The finish is brushed aluminium, and there's even an integrated IR blaster so you can control your TV. Micro HDMI and microSD also feature.
Clearly Sony is determined to come in at a low price point with the 11.6-inch Tap 11, so you can even choose a version with a Pentium processor - it is one of the latest generation Haswell variants, though.
And you can choose up to a latest-gen Core i7. It features 4GB of memory and up to 512GB of SSD storage. It weighs in at a cool 780g, too. The Vaio Tap 11's release date is October 2013.
The second, the Vaio Fit, is actually three Intel laptops with multi-flipping capabilities. This is basically a hybrid device which you can have flat as a tablet, or flip the screen back to be a laptop. It looks like it will be impressively thin, since the whole thing is 20mm thick.
Again available with a variety of processors up to Core i7. The Vaio Fit 13A and Vaio Fit 14A have 13.3-inch, 14-inch and 15.5 inch screens respectively. The Vaio Fit release date is Autumn 2013.
Vaio Tap 21
Finally, we get a new version of the Tap 20, which we first saw at IFA 2012. We're not sure if this is a complete replacement, but the Tap 21 features a larger 21.5-inch Full HD display and aluminium finish - the resolution is an improvement over the Tap 20's 1,600 x 900. As you'd expect, there are latest-generation Haswell processors and you'll be able to choose an SSD or hybrid drive as an option.
