Okay, I know we have some techy types around here and I need some help.

My mom asked for a tablet for Christmas. I was just going to go half with my brother and get her a Kindle Fire. Things didn't work out so I am looking elsewhere.

Honestly, I don't really want to spend over $100 if I can help it, and I figure this weekend is probably the best time to find something.

All I will ever see her using it for is getting on Facebook and checking email.

Criteria for what I am looking for

Around $100
Around 7" screen
At least 8GB of storage
WIFI

I don't really know much about what tablets have for RAM or what kind of processors they have, but of course I'd want something that won't be constantly lagging.

I found this this and wasn't sure if anyone had any opinions. It has 3.5 stars with over 100 reviews.

Any and all advice is appreciated on the matter.
