I use a Samsung 8" device which is very good - unlike iPads you can add additional memory very cheaply in the form of a micro SD card. Very handy if, like me, you like loads of offline maps on your device.
Take a look too at this
https://www.amazon.co.uk/dp/B016BB8V84/ref=psdc_429892031_t2_B014D847FS Lenovo Miix 300 10 inch Tablet - Black which is astonishing value at £120. It runs Windows 10, and can be used as a laptop (with the keyboard attached) or remove the keyboard and use it as a touch screen 10" tablet. I bought one to take away on trips as it will run Basecamp, and again you can add lots of extra memory with a micro SD card. The Windows app 'shop' doesn't have the same range of apps as the Apple or Android stores but TBH 90% of apps for Apple and Android devices are crap and designed solely to hoover up your personal details and contacts lists. For web browsing, email, Office-type functions, weather forecasts etc the Windows device is fine, and probably the best if you want to work with MS Office.
