thanks for all the replies. I would very much like a paid program by data viz if i know it can edit word and excel files, if not i might give free office a try.

I also tried abiword, and i'm not satisfied at all, especially because scrolling is PAINFULLY slow.

Of the all programs i tried the dataviz to go was the best even it it was only viewer and if it is non free.
If they deliver a non free editor that works as smooth as their viewer, i will definetly buy it.

The situation beeing what it is i wouldn't have liked to spend money on their non editor program.
