Microsoft should be able to pull off an adequate tablet version of the main Office apps, that shouldn’t be a big concern. What is up in the air is the pricing for this, and that’s why the rumored iPad version of Office is so significant. It makes sense that tablet versions, iPad or Windows 8, should be priced competitively to similar apps in the app stores. Too highly priced and the Office apps will be poorly received and Microsoft will not compete well. That will result in the failure to recoup the heavy development/support costs this suite will require.
