As I have posted in other threads, Im in agreement with GuyfromNam and Cantafforit above aboutthese being delierately understated controlled leaks, meant to keep the community and tech press engaged and baited, but with a huge surprise to the upside on Feb 9.
Regarding TI's OMAP4 line, here is a link from TI that indicates that the 4430 (1ghz dual core) was being sampled in December/2010 (leaving one to wonder if its in production NOW/Q1/2011) and the 4440 (1.5ghz dual core) will be sampling in Q1/2011, with production slated for 2nd half of 2011:
OMAP™ 4 Platform - OMAP4430/OMAP4440
If I HAD to guess, I'd need to know the release dates of the devices to reasonably guess what CPU's they are running, given the above information; the current leaked information could possibly be accurate and the result of the delayed OMAP4430 chip, which was due to be in production last fall/winter, according to old TI information, which I have posted l here last summer, but, there are other hot dual core chips in production now, other than the Qualcomm chip.
As for the quality of the CPU, I think its fair to say that in order to compete, any CPU will have to perform incredibly well, and if HP/Palm chose the Qualcomm 1.2 CPU for thier WebOSPad, its been particularly tested and run through the paces to make sure it CAN perform as needed - remember, WebOS is uniqwue in that it is a true multitasking OS, which puts a much heavier load on the CPU than iOS and Android, which I believe are deliberately untitutive for running multiple applications simlutaneously, to assure their CPU's arent easily "bogged down"; in webOS, its too easy to open 30 cards, and see the toll on the CPU gradually increase, versus the multi gestured/abstract methods of opening even 10 other applications on Android/iOS
Anyway, just some thoughts to ponder - again, I think we should all be wary of information deliberately "leaked" in situations like this... its always best to keep your expectations reasonable until other rational is provided.
