Minds like you is what ruined commodore, a tablet will be sold in more units than any computer even if it is driven by a exoticOS (= AmigaOS)
AmigaOS would be horrible on a tablet. A decent touch driven UI and apps all need to be made that way from the start/ground up.
Try using an old Windows XP powered tablet or VNC to a desktop on an iPad to see how horrid the experience is.
