Comparing them to today's standards, then yes. However, they gave some serious runs-for-the-money at their release and their price-point in terms of performance was (and still is, really) incredible. It's like spending $175 for an E8200 or $115 for an E4500. Yes, the 8400 is better, but worth $60...eh. Not everyone needs that marginal performance.
But then again, you were what...11 when they were released? No offense, I'm not certain how much stock I'd place in your assessment of them. Unless you knew (real-world applications/testing/use as opposed to reading reviews and Wiki articles) at 11 years old how they worked and why the Netburst ultimately failed, it's a moot point to regurgitate information. Though, I suppose that being all of 15 years young, you ultimately know best, so I'll stfu now...
