Precentral has posted 3rd party app video walkthrough for upcoming Palm Pre. The video above shows applications like Fandango, SprintTV, Nascar, updated Google Maps and PalmOS emulator Classic. The apps on Pre are looking good and switching between applications is also fast.

Still no information about how many apps can run simultaneously. In every Palm Pre demo we have see till now the demonstrator keeps the total number of open cards (open apps) to about 6 or 7, as soon as the number goes higher they start closing cards. This shows that at a give instance Pre would be able to handle about 6 applications running simultaneously.
