Palm Pre better at multi-tasking than the iPhone?

Says Tom Krazit of CNET:

While the iPhone has set the standard for future smartphones, Palm's WebOS delivers two important improvements that the iPhone can't yet match: true multitasking between applications, and a subtle notifications system that doesn't interrupt your train of thought. It does that while unveiling its own stamp on the multitouch user interface that Apple introduced to the masses with the iPhone and finding room for a slide-out hardware keyboard favored by CrackBerry addicts.

I haven't seen an independent evaluation of the Palm Pre's multitasking card system. There must be a limit to how many apps can be open until the system crashes. I like the idea of the alert system, which automatically is reduced to thin text bar, not requiring you to stop your work. The iPhone requires you to dismiss the alert.
