In 1993 I purchased an HP550 Deskjet. It was one of the first inkjet printers that held a black AND colour cartridge and it printed really nicely. I became an HP fanboi even though the printer cost $1,800 and the cartridges a measly $15 each. I had HP machines everywhere and recommended them to friends and customers. Hell, I still remember the local HP Helpdesk number 131 047 and those guys were brilliant. The HP website was IMO one of the easiest to navigate and find drivers for their products at the time.
Now, I would not touch an HP product even if they were giving them away with a 3 year warranty. Their reputation and product quality went downhill so fast that they lost me in less than 6 months. The only HP product I have left is a 2005 iPAQ PDA because it has a good bowling game on it. Now I will only purchase devices that have 3, or 2 years warranty if I absolutely need it now and I don't believe HP have ever had a more than 1 year warranty without paying a kings ransom for extended warranty. A client had an HP LC3 NetServer in 2001 that cost $5,500 (PII 400, 64MB RAM, 4GB HDD) and they wanted $160 for a 3.5" Floppy Drive. I would rather a Greyware Server than something with an HP badge now.
The HP executive must were armoured footwear as they are always shooting themselves in the foot but still manage to keep walking.
