Welcome to the forums.
Before I bought mine on eBay a week ago, I couldn't think of a single good reason for getting one.
After having it a few days, I still can't think of a good reason to have one.
But I've been having fun with it and I can sit back in a recliner and do things I would have to sit up at my laptop to do. Yes, I'm really that lazy.
There lots of helpful info and helpful people here. Have fun!
