You know it occurs to me that at the prices (circa £200) they're just about break-even on what it cost to manufacture them! I think that's really interesting, for HP to try and sell them at a massive loss and the market readjusting itself at a level actually on par with what the product actually costs. Counting HP's cut from software sales through the Catalog they could still be making a profit there.
Just goes to show the painful truth about the tablet market really: if your main competitor has 80% of the market, you can't expect to break into it by selling your own product at the same price point, even if it's slightly better! It seems the major manufacturers just weren't prepared to make the hard decision to take a hit for the first couple of years in order to make enough of a dent in Apple's dominance.
