Galaxy ACE for the mother?

Hi everyone, My moteher is looking to upgerade this christmas and suggested to me the galaxy ace that she had seen on a deal. She only needs to be able text and talk on it, nothing in the way of apps (but im going to try and convert her to using them) or internet.

I was wondering if anyone had used it as ive never seen. I need to know if its laggy in any significant way or if the touchscreen is not very good.

Ive never used a Android phone (Current owner of a HD7) for any significant legnth of time, is it going to be not to complicated for my less than technologicaly gifted mother. And one last thing any suggestions on other phones that would be cheap and more suited. Any help greatly appreciated!!
