LesRS, don't worry about the weight. My Flyer is 20 grams heavier than the Lenovo, I have weak wrists, and it doesn't bother me at all. Even though my case adds a little weight, it made it even easier to hold (better gripping, never cold).
I'd say the A1 is far better than the Fire, simply because even at the same price, you're getting a true Android tablet with expandable storage. You won't have the Amazon carousel, but you can still watch stuff on Amazon if you're a Prime member, download apps (from pretty much anywhere), etc.
