Hiya, in the evenings I spend ages here on Secrets or on FB, Twitter, Google etc. Because I'm using my iPhone I often end up with a headache and also it's not easy to look at maps, lists etc. So, my question is... could I buy a really cheap tablet to use instead? I was thinking wi-fi only, 9 or 10" screen, casing colour irrelevant, doesn't need to be new. Any thoughts please? Thank you.
