1. HP tablet sales fail.
2. HP warns of low earnings, then announces them.
3. Promise to make announcement only after market closes on the 18th.
4. Rumors that they are spinning Compaq back out.
5. Changes mind and makes announcement.
6. They are buying Autonomy (enterprise/IBM space)
7. They are shooting the mobile device effort in the face.
That is... a lot of change to suddenly announce, especially given that the Palm/WebOS aqusition[1] not more than a year ago was the big new vision for the company.They made one product and couldn't sell it[2] and pulled the plug on the entire vision while at the same time announcing a huge corporate shift.
Busy day for HP.
