I don't think circular context menus make a lot of sense for touch based UIs because some part of the menu will always be obscured by your hand. I guess this could be mitigated by having it expand in only one direction based on if the user is right or left handed, but loses a lot of the efficiency of the circular menu. I like how android does the context menu. Long hold and then a scrolling menu shows up. It obscures the entire screen though, so that's not a model for a larger screen netbook.
