Wouldnt bash HP - they can only follow MS - and their HPMSS is/was the class of the field.
MS really seems in poor shape - they seem to be able to do little new right - except if you want to buy a new glitzy game controller

Hopefully they have underpromised (the new date) and they will overdeliver.
As software doesnt grow on trees, sometimes it's delayed even though I was looking forward to this.
Better to wait than to install something that could corrupt the WHS.
BTW - I think HP listened to their customers in agreeing to the update and following through.
