It is a little non-essential indeed, but it naturally has its presence with the truth. Does the designer of the MSN expressions keyboard super-smart and lovely as it? I think unless you never use expressions in the network, you should have a reason to praise it, it is really very convenient and practical.
In addition, the designer also has added a function that you are not likely to think of – each button of an expression when be pulled off is a finger ring, wear it on you will express others the special mood of you outside the network.
