I looked at both when I bought my Dinc 2. The Strat is quite a bit taller and thicker and heavier than the Dinc 2. Not sure if that will make a difference to your Grandma. I love my Dinc 2 and if you put one of the good keyboards (Swiftkey, Swype, etc.) I'm sure she will do fine w/o a hardware KB. Love my Dinc 2.
