a bit of a sidetrack, but what's the difference between the ARM11 600mhz and Arm Cortex A8 600mhz. I'm a total processor IDIOT, but just wondering how big of a difference there is between the two in terms of processing. :) thanks!

No, I do not. Maybe you can clarify what you mean?

So the "real multitasking" simply means "more windows visible at once" for you? Why not just say so?

I prefer the current way of having one window and quick switching functionality. And I am calling it real multitasking too ;-)

As for TV-out - it has even less pixels than the display so huge screen does not buy you much except blurriness (NTSC is 720 x 480, PAL is 720 x 576, both are interlaced).

BTW is the TV-out only composite (no s-video)?

My thoughts exactly. Having multiple windows open side by side isn't really feasible until you start hitting resolutions like SXGA and higher... even XGA screens make it really difficult. A web browser/word processor or whatever else is relatively difficult to use with less than, say, 800px width - that gives you 224px of width left on a 1024x768 screen, which is pretty much useless for anything other than an instant messenger or a (tiny) file manager window...

Yes, composite only.

Btw, I was really worried about the ram on the n900 before I got it. Multitasking was a big problem on the n810, especially because when you turned it on its RAM was almost already full.

But multitasking really does work fine on the N900. I do just naturally close stuff more aggressively then I do on a computer. But you can easily browse the web, listen to music, have your email client and contact list open etc. So I have to say Nokia made the right call with the 256 of RAM. We should remember that the swap is much faster on the N900 then on your computer since its SSD (though truthfully not sure how much I make the N900 swap).

My Q8200 desktop with 6 gigs of DDR3 and Nividia 9800 lags with mulitple video and Flash running in the background.

We need practical perspective applied here IMO.

Arm 11 has less transisters so less power to execute operations efficiently and takes more power to execute the same operations.

Kind of like comparing a Pentium 3 to a Pentium 4 at same speeds.

Actually a greater difference than that, especially considering the Arm 8 supports discrete DSP and GPUs.

Heck, the integrated functions kick Arm 11's butt even without external DSP or GPU.

I hope 256 MB RAM will be enough to run a few KDE programs (no KDE desktop). e.g. I really like ktimetracker.
After taking a sizable hit in the form of loading several shared objects, and running a few harmless daemons, I hope to still be able to switch back and forth efficiently between several apps.
On my n810 I always end up swapping.
