fair enough if you need dedicated software for that, then this obviously isn't going to work for you in a business sense, if you watch the keynote speech, the iWork demo's were pretty impressive so it is feasible for some that they could work on this away from home, just depends what sort of work you need to do.
I see a lot of potential for the apps, the demo's that had been worked on for just two weeks were a good intro, hopefully with a few months to work there will be some truly useful apps in there.
