Hi I would like to buy a new computer for work. I need something reliable and fast with Windows. My budget is 700 to 1000 euros. I am looking at two HP computers on sale at the moment: a ProBook http://store.hp.com/FranceStore/Merch/Product.aspx?id=Y8A75ET&opt=ABF&mastersku=Y8A75ET&masteropt=ABF&sel=NTB& - there is a big reduction on the ProBook, and I am wondering why, is it an old model? and a Pavillon http://store.hp.com/FranceStore/Merch/Product.aspx?id=1NB32EA&opt=ABF&sel=NTB. Which one do you think is better?
