The touch screen issue on the Surface 2 never properly went away. It would work for a while, then often after a restart it would stop working. About 50% of the time it would come back after the battery ran flat, so I got through the last ~6 months by keeping it powered up whenever the screen was working, and if it did go flat and the screen stopped responding to touch I’d let it go flat again and try again.
I had already recommended my brother to purchase a S3 which he did and he was very happy with it. So when it spent the last month with the screen stuck not working something had to happen. I got approval through work to upgrade to the Surface 3 so I utilised the extended warranty to get a refund rather than just change over to another S2 unit.
So I’ve now got a 64Gb Surface 3 with a grey Type Cover, Surface pen, video adapter and (aftermarket) screen protector. Time will tell how this one behaves!
