intel SU4100 - how does it rate?

[joe pineapples]

Knowing very little about the world of laptops, i wanted to look into this for someone consdering the Acer Timeline 5810TZG. Rest of the spec looks ok, but i wondered if that long battery life meant a slow laptop. She does some basic DTP, net usage, and uses an audio authoring program called sharm.

thanks
