Question about tablets

[SpywareDr]

I just called Paypal, who I have an account with. Their mobile payment system doesn't accept "Android" -- they're working on it....Wow! you would think Everybody would have an android compat. system by now.

SquareUp allows you to accept credit card payments anywhere with your iPhone, Android or iPad.

Question -- with these tablets, can they be easily upgraded like desktops -- for example, ram?

No, not at all. (It costs more to make stuff removable).
