As much as I detest the man's lack of leadership, Carty's strength has always been finance, and he was AMR's CFO for at least five years before moving into the president's office. He's also no stranger to Dell -- he served on their board for many years as an external director.
So while Ronald is right about the brand awareness (definitely tied more to their marketing than their product), but in the server world, they've been surpassed by HP/Compaq and IBM for at least the past four or five years. Likewise with busines desktops and notebooks.
Sadly, since Michael Dell stepped back, they've focused more on the home business, and less in the business sector. Their quality dropped, and that drove many corporations to stop buying Dell for their data centers and corporate desktops. Home sales are great, but corporate sales are where the profit margins come from (not at all unlike the airlines in that aspect...).
After Carty was deposed in 2003, AMR's CIO probably thought it was best to make a gesture of allegiance to Arpey, and issued a decree to never buy Dell again. Since their quality had fallen, I didn't mind the switch to HP/Compaq, but most of my pre-2002 Dells are still running just fine from what I'm told, even though several of the newer servers have already been replaced. If their quality were still at 2002 levels, I would still be buying Dell today. Instead, I spend upward of $50K per year with HP, and they stand to earn at least $250K from me in 2007 and 2008.
And even PlaneBusiness.com abandoned Dell last year (after seven or eight years of running on Dell servers) in favor of Apple servers.
Totally agree on their poor customer service. Even as a large corporate customer, I gave up trying to get service on my last Dell after repeated calls to India, finally reached someone in AUS at their HDQ by blind dialing into their switchboard, and didn't hang up until I got a return authorization.
Since then, I've switched over to HP and have had no regrets.
