"saved state" to a card is not true multitasking! webOS multitasks no better than Garnet does - in fact - less so!
if it was true multitasking, the cards would be truly active when minimized! not simply snapshots of the screen! same goes for bookmarks! for instance, why can't i watch Sprint TV in a minimized card and scroll through a word doc right next to it? answer - because only one true app is running at a time.
IMO the REAL reason that Palm put the kibosh on TealOS is because they didn't want their secret to get out - that this OS doesn't truly multitask - at least not the way they originally presented it at CES. it's all smoke and mirrors. saving multiple launchers as screenshots as saved states (by open-close-open) is not multitasking!!!!!!! hence the lag and delay switching through apps - yet they eat up resources regardless. SMOKE AND MIRRORS and the brilliant guys at Teal figured it out. Palm wasn't afraid of TealOS taking Pre sales - it was afraid of them exposing their secret.
