You may want to consider the Samsung Galaxy Note Pro 12.2 but I'm not sure that it on sale in UK yet. I have an ASUS 11.6" ultraportable laptop which could be as light and as user friendly as a tablet at that size.
Thanks Woolwell. I might hang on and await UK pricing on the Samsung Series 7 laptop, I should have mentioned I need touch screen.
I've got the normal Galaxy Note 2, and I've had a Galaxy 7 inch, the trouble with Samsung Android devices is the amount of dross that Samsung insist on pre-installing, and the length of time they make customers wait for o/s upgrades.
