Re: Not bad...
If anyone thinks specifications other than those that can be perceived directly like screen size sell phones then they're living in a fantasy world. Customer satisfaction is the main factor, both by word of mouth and because salespeople understand that their commission is safer if they push a phone with a low return rate. Hence Samsung are rightly being rewarded for launching the latest in a pretty decent series of phones.
Clock rates, core counts, memory sizes, etc, mean basically nothing unless and until they actually become detrimental to the user experience.
For evidence of this from the other direction, see any of the postmortems on Windows Phone 7. No-one has ever said 'it would have succeeded except that customers are no longer willing to buy single core phones' and of the did they'd be laughed at.
