Hello everyone that helped me decide on a tablet.
Thank you for all your help and advice.
In the end I decided to go with android due to expandable storage and chromecast native support which i am loving. However as I was about to purchase an "Xperia Z2 Tablet" I spotted the "Samsung Galaxy Note Pro 12.2" was marked from £650 down to £325.
The spec was too good to pass on with:
- 12.2" Screen 2560 x 1600
- Quad 1.9 GHZ cores with an additional Quad 1.3 GHZ cores
- 3GB RAM
- 32GB onboard Memory
- Expandable Storage via Micro SD (128GB supported)
- S-Pen support
- USB 3.0 port
- Enhanced Multi Window (use 4 apps at once)
- Screen write (I can doodle on my screen with the S-Pen and save it as an image and then use all-cast to put it on my TV for my group to see what maps i have drawn)
its Fantastic and I love it to bits
reading Pathfinder and Dungeons and Dragons PDFs on it has been a joy.
Thank you everyone once more for all your help
