Sony Satio has the same hardware as N900 and yet it doesn't even do HD and taking picture with it at full resolution tooks like 10seconds to processed the image.

what I have read about the issue, the bottleneck probably is the bus between camera and cpu,gpu etc. wasn't it the same issue with n8x0s? hardware was capable for better video output but the bus was totally undersized for such functionality.
e: and ps.
raw video would be the easiest job for every component

depending on what you meant by better. TI is better than Qualcomm yes. Snapdragon is still better than whatever OMAP3430. True, n900 can overclocking to the same spec but Mhz is not everything. The processor is not natively running at the Mhz level is not the same the processor running at native frequency. Otherwise why would they made OMAP35xx or OMAP36XX if overclocking cpu can hit the Mhz and give out the same performance?
True that A8 is better than Snapdragon because of the GPU built inside A8. But the one in N900 is underpower in term of achieving 720p at 30pfs like Desire.
Snapdragon doesn't have GPU on the dice. But android OS doesn't do multi tasking and CPU will be free to work on video processing not to mention 578MB RAM

But there is no way to get 720p recording or play back to work with the N900 smoothly. Maemo5 just doesn't have the spark of HD in it. MeeGo might have some future with HD if it ever coming to N900 by official.
I can see Samsung Omnia HD has the same hardware as the N900 and I accepted that it is pretty sad to see N900 falling behind in this area. Also N900 use up more RAM and seems to be struggle in image processing.
Only Nokia can fix this. Nokia closed apps and information doesn't really help us here to tackle the problem and find our own solution. Anyway, yeah

This is IMHO incorrect. The problem with the N900 not recording @720p is because of the software, not because the hardware. When the device access to the flash, it usually gets stalled, and this is a known problem with the Linux Kernel. The main problem is that Nokia most probably is not going to backport the patches to the N900's kernel, so we will have to wait for Harmattan.
Yes, it does. Even iphone's os is multi-tasking. Every big OS has services/daemons that run in the background.
