Sounds better?
Sorry fella, but this is confused.

Multitasking, by definition, increases demand on two fundamental resources - memory and CPU. It doesn't 'slow things down' in the sense that it causes the CPU to run slower - it will always be chugging along at 600MHz or whatever - but it can have an appreciable effect on the performance of individual programs, 'slowing' their responsiveness, making them 'feel' sluggish.

You may not experience any appreciable slowdown when you run a particular set of programs together, but that will depend entirely on the demands each particular program is placing on these resources.

Try running multiple youtube videos, or open a few xterms and run htop in each....then you'll get an idea of what it will take to make your device start to sweat. I imagine older devices will sweat earlier than later (N900) devices.

In short - the degree to which multitasking impacts overall performance will depend on the particular resource-demand characteristics of the specific software being used.
