i dont think you followed the webos developing detail, webapp is different idea than what webos is allowing. and it will convincing no one to claim safari's web app is anything remotely close to true "multi-tasking".Except it doesn't because not all desktop apps are locally hosted webapps written in javascript, like they are on the Pre.
But you can run multiple web apps in Safari with no problem (and you can flick between using a card like interface, just like on the Pré), so on a technical level they're absolutely neck and neck.
If we're talking about multitasking involving real, compiled applications, then the Pré doesn't do this at the moment. Google's Android (which is Linux based) can but it has a detrimental affect on all the above.
Where we disagree is that you seem to be under the impression Apple has delivered a immature platform that is of little technological importance, whereas I believe that couldn't be further from the truth.
The Pre offers desktop level multi-tasking experiences, and its best so far on a mobile device, More than technical issues, the user experiences will be at a completely different level than any current smartphones in the market (iPhone included), which are all, one way or the other, glorified app launchers.
My point is apple technically isn't capable of developing a good mobile os. I dont expect people here to agree, but I do want to put it out.
for topics about sales, innovations, revolutions, good or bad. I really have no interest to debate it since there is absolutely zero data to support any comparison. I will leave that to a later discussion.
