The iPhone 4 use ThreadX RTOS in the Infineon PMB9800, or X-Gold 618 baseband chip/cpu.

Separate = higher cost, more complex HW and higher power consumption.
Marginally more. You gain a lot in isolating the baseband, namely you remove RTOS dependencies from the OS on the applications processor and simplify the interface for the OS down to something known (Serial, USB) and the communications protocol (like the N900's phonet interface.)

It also allows the OS to be fully open and user-replaceable, unlike Symbian which has never (and is still not) been user replaceable. Overall it's an improvement.

This, by the way, is the way Android does it too. My baseband version is changeable and I can install any number of basebands available for my Droid. This might explain why Androids always seem to be far more snappier and better in general as phones than the N900.

Maybe, $0.99 is popular... But 0$ and open-source are more popular, I hope. Though it's difficult to compare...

Quality isn't quantity. Compare: two or three (don't remember) different theremins in iPhone app store, all with 0.99$ price, and one free open-source theremin on maemo.org.

And centralized app store gives artificial restrictions. Would it be possible to have unlocked FM transceiver if the only way to install an application was through centralized censored App Store?

Somewhat subjective.

I wasn't making a case of one being better than the other. I was making a point of how different they are and the 'advent' of a workable pattern for a commercial appstore is a significant step forward to a 'digital future'.

FOSS repositories will continue (its underground-ish) existence and AppStores will continue to take up the limelight and create interesting online marketplaces.

Well, having a changeable baseband just lets you unlock the device (GSM) or fix bugs.

This might explain why Androids always seem to be far more snappier and better in general as phones than the N900.
The N900 works in the same fashion. Not sure of the physical interface, but the baseband in the N900 (indeed, anything more advanced than your typical dumbphone and definitely anything that could possibly be unlocked) runs on its own processor.

The "snappiness" is definitely for other reasons.
