Thank you for your answer about the Celeron!
However I will maybe start a war here, but Google Office is a crap to me. I am working with MS office only. When you really need to work with excel (not just the basic budget computation) there is no real other choice than MS. Aple or Google despite providing interesting tools to compete with PPT and Word are just no match with Excel.
And most of my offline work is related to data management and I use Excel a lot, thus offline chrome is no use for me^^
But I can understand someone could find it adapted to his/her needs, but it doesn't fit to mine ^^
Thank you for the answer anyway!
PS: I almost don't play, but when I do it it's only on "heavy" games. I don't enjoy the time-killer games...
