I think a lot of the complaints are not from N900. People usually like their N900s, but they do fear for its future and whether they would end up with an obsolete device in a year's time. The main reason for this is Nokia's attitude. IMHO, following are the main reasons why people are complaining and many of them are legitimate:

1. When they bought N900, they thought they were buying into a platform which would form the basis of Nokia's smartphone entry. However, then came Meego and the news that N900 won't be officially supported
2. A lot of people (that includes me btw) were hoping that with the N900, Nokia would hopefully finally get the new dynamics in the post iPhone world that it is not about hardware anymore. With Apple supporting its two year old phones in the new firmware upgrade, I think people find Nokia's contrasting attitude very disappointing. Personally, I think Nokia shot themselves in the foot here by treating their most loyal customers shabbily. I have been leading NPD for the last 10 years and there is anything I have learned is to keep your core customers. Nokia should probably go and study about NPS (Net promoter score) and network effects
3. Last and probably the biggest reason is Nokia's selective open source adoption. Nokia adopted open source when it suited them i.e. getting a lot of pre built software and application echo system without having to do the work themselves. However, they left the other half out about open communications and transparent roadmaps. Again, as anyone who has studied economics and Nash equilibrium would tell you that open roadmaps are actually great for both customer retention and also to make sure your competitors don't enter your markets. That is one of the reason Apple announced the features of their next OS as many of the Apple loyalists had started cribbing about lack of multitasking etc. Nokia however are all about keeping mum. There are genuine reasons for that as that gives you more flexibility, but in this case that is causing more harm than good

So yes, IMHO Nokia have actually screwed many things up with N900. As I said, having headed product development in associated industries, I can see too many holes in the process to say Nokia is blame free here. But I am not worried because Nokia will actually have to pay for it in the medium term. Justifying actions to users never works retrospectively. You have to manage their expectations from the very beginning, which is what wasn't done in this case.

I really don't understand why all the arguments going on here about nothing but false representations basically.
Just for the record if you look at the N900's hardware it actually has everything that a Symbian mobile phone has and more a lot more!.
What we are talking here is software nothing more needed as the hardware is all there for anything that would be written for android and symbian apart from a digital compass.
The rest of the arguments have absolutely no ground whatsoever as it is only a matter of time before it all comes together software wise.

The very first point the OP made was

"There is no 3G Video Calling The Nokia N900 is not a phone designed for this. Infact it is a Mobile Computer with phone capabilities"

What are you talking about here because the N900 does indeed have 3G capabilities and the rest of it is down to software and a 3G signal being present on both sides
If you base your counter defence in that way you will make yourself look very silly indeed and the very reason you need to re-word everything as you started off on the wrong foot.
Anything available on Android or Symbian will eventually be available on the N900 (android has already been ported to the N900 on this very forum if you care to look) and as it IS a computer in it's own rite and all the hardware capabilities are already incorporated in the hardware of the N900 so the arguments stop there.

Please stop the drivel and get on with the developments in hand that will make this device into what it was portrayed as a "FLAGSHIP" mobile device from Nokia IT DOES NOT NEED DEFENDING !!
.

And another arguement pops up now. some people say this is not a Flagship device.

Portrayed is an interesting word .

How does a phone get the distinction of being a "Flagship" do the mfgrs. give it that distinction, or is it a title awarded by sales?

I completely agree with what your thinking and that the point of sales should indeed make it a "flagship" device but in the case of the N900 it was indeed portrayed by sellers and the maker Nokia as a flagship mobile phone/computer.

I have provided some solutions if you read thoroughly but I'll edit my post so it is explicit.

AHHHH this is totally pointless.

Ha ha... that is spot on. Too many circular arguments.

Yes but we all love the Nokia N900 and wish to continue its prosperity by recognising it's faults and improving upon them even if they are minor.

You really do need to get to know the community on which your posting because i can tell you from personal experiance it can get dammm right nasty and argumentative.
Right now everyone that bought this device is not amused to say the least so you coming on here trying to make out at this moment in time its such a fantastic device will only start arguments and you will get attacked on here.
Wait a little while untill some headway is made on the OS and in particular some decent apps appear then you will have no problems in defending the N900 but untill then your on very shaky ground.

Well I love the N900 and I think it is good with almost no problems. Other's think the problems are worse than what I perceive and I would like to try and convince them otherwise or help them with a way to fix it. I will add any contributions to the first thread post provided they are helpful.
