Aloha and welcome aboard!
Don't know anything about those new fangled do dads but get along with this old beater PC pretty well.
Got a cell phone awhile back and know how to make phone calls.
It depends on what you are wanting to do. I definitely would recommend going with the computer. I have an Ipad (One) and still finds it is limiting to what I use a computer for. I am an avid photographer and love editing my photos the same day. This is just my opinion though.
