- it does run 100 problem free on 5700, haven't encountered a single error yet in last 2-3 months
So you've purchased games without any problems? Or have you just used pirated games? I did ask this before, but you didn't answer.
If you haven't purchased any games, then you haven't tested it properly. The only way N-Gage can exist in the long term is if people buy the games.
N lastly, quite frankly, there's literally no difference between N81 and 5700/6120 except the fact that N81 has special gaming keys, 0.2 inches bigger screen n double the amount of ram.
First of all, I personally reviewed the 5700 and 6120 for All About Symbian, and the N81 for my own Nokia Duck site:

I also reviewed the 6110 and 6290, which are very similar to the 5700 and 6120. So I do know these phones very well indeed, I spent many weeks using each of them.
They're not quite as identical as you're claiming. You can't say there's "literally no difference".
The N81 does indeed have twice as much free RAM as the 6120 or 5700, and that's not something you can just ignore or dismiss. Some apps depend on a large amount of RAM to run properly, or to run at all. When the RAM runs out on a device it starts working strangely and then it crashes, so anything which takes the RAM to its limit is potentially going to cause problems.
I suspect it's exactly this which is causing Nokia such problems with getting official support for the N73 and N93, because they have much less free RAM than the other official models.
In fact there is some evidence for this: the N-Gage application tells N95 owners to update to a newer version of the firmware before they can install it. This newer firmware increases the amount of free RAM in the N95 from 20 megabytes to 30 megabytes. 20 megabytes is how much free RAM the N73, N93, 6120, 5700, 6110 and 6290 have, so it could be that the extra 10 megabytes makes all the difference.
It's nokia's beloved baby, 5700/6120 isn't, they didn't sell that much rather weren't hyped like the former.
The 6120 most definitely DID sell a lot, it's one of Nokia's most popular S60 models due to its extremely small size and very low price.
Some people claim it's Nokia trying to push their more expensive models. But that can't be true because the next N-Gage model is the 5320, which is the cheapest S60 model Nokia has ever made.
And none of that explains why N-Gage hasn't officially appeared on the N73 or N93 yet, even though Nokia said it would. Why would they announce it and then hold it back? It can't be deliberate because it just makes Nokia look really bad, they've severely annoyed N73 and N93 owners who were promised N-Gage support.
The only thing that makes sense is that Nokia tried to add N-Gage to the N73 and N93 but ran into unexpected technical problems.
If the issue is free RAM, then those same technical problems may be holding Nokia back from putting N-Gage on the 6120, 5700, 6290 and 6110 because they all have a similar amount of RAM to the N73 and N93.
ngage compatibility on every future s60v3? No way. I still feel that it will be restricted to Nseries with exception of 5320 ( nokia certainly trying desperately to reach mass that's why the would be cheapest s60 got support )
Why would Nokia want to deliberately restrict N-Gage to just a few models? How would that benefit them? I know they've restricted it, but I don't think it's something they want to do.
If they've got a choice between all S60 users being able to buy games, or just some of them, why wouldn't they choose all?
N-Gage isn't about promoting phone sales. Most people don't buy phones for gaming, because most people don't play games on their phone. N-Gage being or not being on a phone won't make much difference to how well the phone sells.
The point of N-Gage is to sell as many games as possible, and you can sell the most games when you have the most people using compatible hardware.
Nokia is trying to become an internet services company instead of just a hardware company, because hardware profits are going down as the average price of phones goes down. Eventually phones probably won't be very profitable any more, so Nokia needs a plan B for when that happens. Their services are being sold under the "Ovi" brand, and N-Gage is part of Ovi:
