They are able of the best and the worst at the same time:
Their old COMPAQ laptop division who's now called Elitebook are in the top best machines. But their consumer branch (Pavillon) are the worst machine ever made.
They have a good marketing, they are everywhere and everybody use their product but not many people loved them. When you have warranty the service is great but if you don't and it is a common issue, they will deny the problems, and wait for a court order before making a recall which they will fix by putting exactly the same flawed part. I have tons of broken HP machine coming to my office and it is always a well-known common problem.
They make good printer, but they load their half working driver with crap, spyware, crapware... They also are responsible for the ink markup, they encourage customer to buy a new printer every time the ink runs out. They spy their competitor and their customer.
I don't know where they are going with palm, I don't even know if it will be for better or worst....
