Compare the responsiveness of OS2007 and OS2008. OS2007 is obviously faster and more stable. Shouldn't a newer version be at LEAST the same quality?
Do you own a N810? Maybe because of the physical keyboard, it makes the issues not as noticeable. If you have an N800, install OS2008 use for a couple of days without stylus, then install OS2007 and use without stylus as well. Switching back to OS2008 will probably start to annoy you, unless you bring out the stylus.
Have you seen my bug links? Touch goes to random places (with or without stylus). Finger keyboard does not launch on touch. Come on, these issues are not present in Os2007 but continues to exist in Os2008.
