What do you want it for? That is the primary question.
If office work / internet browsing and such non-demanding tasks, it will be perfect. If you are into gaming, CD/DVD creation and so on, it will be less suitable.
I actually saw them yesterday and thought that they would be fine for an office - but the shared graphics would imply that an immediate boost would be gained by upgrading RAM to 512mb. I think that graphics were limited at 64mb - basic but ok for DVD watching, little else.
