For a $400 notebook, the HP Pavilion is a very good machine... For $400, I really didn't expect a top-of-the-line performer. This is my "fun" laptop. In the great big world of business, you would not be happy with this notebook. It's a $400 laptop. How important is your business?
The graphics are good; a 15.6" screen is good for viewing video; Refresh speed is good; It does not hiccup when multi-tasking (there is a limit); Microsoft Excel functionality and speed is better than I expected; I can't really complain; Web browsing is better than adequate.
Battery life could be better; The casing could be more rugged; I would not recommend putting anything on top of the notebook when it is closed; Then again, I don't recommend using any laptop as a shelf to hold stuff; The AMD dual core processor chip is adequate; I only paid $400.
