For a decent counterpoint, see here[1]. Ignore the pro-murdoch spiel in there, much as you'd hopefully ignore the apple sycopanthy from Gruber.
Personally I don't see the Daily as a failure. Of all the newspapers I see online in the UK, the only ones making money from it are the Times (with it's paywall) and so on. The Daily was a good experiment but ultimately would've suffered more from limited market sizes (why not web? why not android? why not every platform and a html5 backend?), but fundamentally I suspect what killed the daily off (at least for the UK) was the Times iPad edition. With it, Murdoch has a dead tree and online version and is making money from both. Thus, the need for the Daily (still running at a loss) to exist is gone, but you can bet that the Times iPad was definitely influenced by the Daily.
