I have a Sony Vaio Duo 11" Tablet which hasn't had much use unfortunately.
It has a keyboard built-in underneath which slides out.
The battery life still is like new gets just over 4 hours.

It is surplus to requirements.
I purchased it from Jb Hifi early last year is in mint condition.

The tablet has a proper Active stylus so you can rest your hand on the screen while you write.
I've found it useful having 2 USB 3 ports, HDMI, VGA and Ethernet which is rare to find on a tablet.

I would prefer pickup from Auckland

Looking for $800 which includes Active Stylus, Sony Sleeve for it (which was silly overpriced), charger & tablet)
