The best thing can be done is get back Mark Hurd and resuscitate PC, Notebook as well as make quality printer (HP middle tier printer sucks btw - shake the table, make shagging noise).
The next best thing is perhaps get one of the Hewlett or Packard descendent back into the business.
The worst thing is what being done now. So I guess we will all just eat our popcorn and follow the drama entitled "The Unmaking of HP" this next few years.
