Actually HP was in pretty good shape prior to Carly; post Carly (2005), the stock was worth less than it was in 1999 when she took over while Dell's and IBM's stock had increased. Besides the "Invent" tagline, I don't think anyone can point to anything good that came out of her tenure at HP. Lots of revisionist history being put out by her team and supporters.
Well, some would argue that 1999 should be remembered as HP's "horrible year", they spun off Agilent (which is very healthy and profitable now) and appointed the wrong person to lead the "newly refocused" HP.
