Buying Palm was nonsense. HP was never the company to make it work. Contrary to that, Autonomy, one of the best software companies in the world, is a good fit for HP's enterprise strategy.
Spinning off the PC business is very likely a step towards selling it altogether, similar to what IBM did years ago.
I think these are all steps in the right direction and I'm thinking of buying the stock once the current stock market panic has settled down a bit.
