Once again, thank you to you both. I'm extremely grateful for all your technical expertise and advice, and patience!
It's all beginning to make sense, and it's sounding as though I will be getting some type of tablet. I don't think it sounds like much of a steep learning curve for what I want to use it for. And I agree, games I play on PC or PS3!

This will mainly be surfing/reading. I think I'll try to get to a store where I can see hopefully a couple of these beside each other and do some comparison. After that it's just a learning curve and seeing just how different it is on my eyes. If brightness/contrast can be manipulated favorably, I'm thinking it's just a matter of which tablet, and likely PB unless a great deal comes in the next month [which is why I wanted to learn about these now].
I can't thank you enough for your patience and kindness...
