Questionable battery life improvements aside, Demand Paging's benefits in term of free RAM alone would make it invaluable for pre-P1 UIQ 3 smartphones.
Releasing it in a FW update for these devices would be the decent thing for SE to do.....however what SE should do for their smartphone customers has been discussed ad nauseam on other threads already

Do you think SE is capable in making our uiq 3 phones to do the demand paging??

demand paging is huge.. and i don't think it's a question about whether or not we'd want it more about whether or not SE can deliver it...

Demand pagind is supported in Symbian 9.3. (Nokia backward ported it to n95 symbian 9.2). All SE needs to do is upgrade UIQ3 to support the newer core for future UIQ3 phones.
But I think it would be more difficult for SE to do backward port for current UIQ devices (like p990, p1) as the symbian used in these devices is much older than N95's v9.2 . And like everyone else is saying, SE would not spare the effort to do this.

So UIQ3 does not implement demand paging. That could be an explain for why WM5 devices with the same amount of RAM are having much less issues with memory. Windows CE, which Windows Mobile is based on, has had demand paging for quite some time, introduced in 1997 with version 2.0 if I'm not wrong.

I strongly agree
SE can do it if they want, but given the fact that P990/W950/M600 is in their EOL stage and newer UIQs i.e. P1 & W960 boots up with very generous free RAM. i doubt that will happen. Maybe Motorola could do that for their RIZRs as their phone have the least amount of ram available for applications among all symbians (only 50Mb in total) but the lack of ram doesn't make negative feedbacks on the phone's general performance specifically the Boot time as they used the M-RAM isntead of SDRAM in which the former did not need battery juice to run and process boot files for the system
But I think it would be more difficult for SE to do backward port for current UIQ devices (like p990, p1) as the symbian used in these devices is much older than N95's v9.2 .
that's not impossible imho, but yes it's more difficult for SE to do as it would take more time for them compared to nokia given the fact that SE has a smaller symbian developer community than nokia.
SE's demand paging backport to support UIQ 3 sym. 9.1 will be similar as to what StyleTap have made to enable UIQ 3/S60 to run Palm apps. imagine the possibility that could be

However demand paging requires well written code and seems to work best with well designed software libraries.
Given SE's shaky track record with UIQ firmware, I'd add that it should be offered for UIQ 3 devices (especially those short on RAM) only
if they can implement it properly.
Otherwise they're better off leaving it alone.
(This is a lovely thought-experiment, BTW, because interesting as all this discussion is, it's never gonna happen
Still, it's interesting to see what these purely hypothetical discussions turn up as they progress)

SE should fully implement it for p990 users. These people paid good money in good faith for a device which has not been properly supported.
SE have a moral obligation, in fact it could even be said to be a legal requirement to fix these handsets. UK trading laws are quite strict, anything sold has to be fit for the purpose its being sold for, SE need to do this to gain some respect back from people who - quite rightly - feel ripped off by the p990.

but tbh, i want demand paging for P990 and W950/M600 phones

@razec, you have valid points but I think @aqualung has quite clearly explained the situation. SE will never even attempt to consider the notion of demand paging for the P990. We have seen in the past that their attitude is "we know there is a problem but we can't fix it so buy the new model in which we were able to hide the problems better".
Guys, just think. SE was barely able to get a moderately stable version out which took them two attempts and they still couldn't get it right. How can we logically expect them to implement something like demand paging when their current fw is still incapable of determining if there is new update available or not?
Bottom line is, I don't want SE to attempt this since I don't want to spend the next year or two waiting for bug fixes to make the P990 usable again.
