What is it with HP and upgrades?

Official: HP iPAQ hw6500 no Windows Mobile 5 Upgrade @ Dave's iPAQ: "therefore HP will not provide MS Windows Mobile 5.0 on the iPAQ h6300 and hw6500 models"

Hmm, I have an iPaq 5550; HP refuse to upgrade that from Pocket PC 2003. When I upgrade I will look at each vendors record of upgrades (You have been warned - my masive upgrade budget is up for grabs :-) )
