Tablet - What are the advantages and disadvantages?

[_Cathy_]

My 80+ year old Aunt called me now because she can't decide if she should buy a tablet - it's 4 am in CA! I told her not to buy anymore since she already has a smart phone (Samsung) with a large enough screen. I forgot the model but it's almost as large as my Note 9. Last year I taught her how to viber and youtube, and it looks like she really enjoyed learning this "new" technology. I have a tablet that came with my Note 9 and I just gave it to my Mom. My Mom does not use it that much because I also gave her a smart phone.

I advised my Aunt not to buy anymore but she told me to list the pros and cons of owning a tablet. I want my Aunt to make an informed decision (I love her to bits!) so please help Here are my list

PRO
Larger screen

CONS
Can't carry around (too bulky or heavy)
Redundant if you already have a smart phone
Additional Payment for Tablet
Additional Payment for Internet (her phone's data is connected to my cousin)

Those are the only points I could think about...
