When an option is selected, there seems to be a noticeable delay of about 1/2 second before the device responds - Very slow internal storage?, Overworked CPU? I don't know.

In almost every demonstration video of Multitasking, the user has to tap the screen a few times to switch tasks, almost like the CPU goes to 100% busy for a short period of time - particularly after starting the music player and if you listen carefully the music is jittery when switching tasks.

Task-Switching is not Multitasking, having said that, the N900 seems good at Task-Switching given that most the apps demonstrated are actually doing nothing e.g. IM, web page, etc. these are all 100% idle apps waiting for input.
I don't understand, technically I don't think the Cortex A8 is SMP or HT in any sense. So yes it is Task Switching in a sense. Actually its called time sharing I believe. I am pretty sure IM, Web Pages etc ain't IDLE either. They would be doing data transfers in the background like html refresh, IM status updates etc.

Also please give more information like video, firmware versions, installed additional software, running processes.

Thank you.
