I don't understand where you're getting the $23mm/quarter number. The last quarterly numbers I saw for Apple were just under 10 million iPads sold; using the $200/tablet and $15 profit numbers I gave before, that'd be $150mm profit on $2Bn revenue. Those aren't "blow your socks off" numbers, but they're not "disaster" numbers either (whereas what actually happened with the TouchPad
was a disaster.) Numbers like that are at least viable for a major strategic initiative for a company like HP, provided there's sufficient
motivation for such an initiative.
With the market leader making $200/unit and you making $15/unit, they could put you out of business if they're at a comparable price point. But if the competition's $600 iPad cuts its price to $550 or even $500, it's not going to pull a lot of customers away from your $200 hPad; you're serving very different segments of the market. Similarly, a 10% price cut by Maserati wouldn't threaten Cooper Mini sales.
I'm not saying HP necessarily made the wrong move here. I'm just saying, I don't think you have to be a "big dummy" to think there's room for a low cost, low margin tablet that makes some profit from software.
