I use Office 2007 VL Enterprise on a laptop and on a desktop, it is CLEARLY much fater than 2003 dreamed of being. I really like Office 2007 a lot. It is clean fast, and it saves well and in many formats using save as.
Long live Office 2007! Works 8...ha!
Not sure if you realize this but for quite some time now Works has been based on Word 2003, it simply has a highly ANNOYING template set that runs on top of it.
So even if "most windows pcs" came with work(not true in any regard) it would not have what you have.
