i tried out very briefly google documents for xls. it does not translate xls sheets perfectly which is pretty annoying if you've spent a lot of time working on getting your sheet exactly. which i have. also, it doesn't show your formula at the top which is something i use quite a bit. so, for free stuff, it's probably not bad, but there is def. some funcationality that is lost in translation. as much as i dislike the ubiquitousness of microsoft, excel is a pretty good program.
I think i'm just a control freak and i don't like it when programs do funky things to my files.
