"Indeed krisse, it seems strange for Nokia to boast they've released the largest resolution phone camera when it is not comparable to a cheap digital camera of equal or lesser resolution."
It's not strange if you look at it from Nokia's point of view: at the end of the day they're there to provide what their customers want to buy.
Many many customers simply demand higher and higher megapixel counts whether or not they're of any practical value. If the customer wants it, Nokia is obliged to provide it or else the customer might buy someone else's phone instead.
You can imagine the scene in a shop: "Oh, this phone has more megapixels, it must be better, I'll buy this one." They don't always appreciate that a high quality lower megapixel camera can sometimes actually achieve better results, these kind of end users just want more raw performance, raw horsepower.
There are many people who buy devices based almost entirely on their statistics, it's a sort of Top Trumps approach to technology. 😊
Part of the blame for this lies with PC technology: people have gotten used to bigger HDDs always being better than smaller ones, large amounts of RAM always being better than small amounts, faster processors always being better than slower ones. They apply the same logic to photos, audio and video, without realising that anything which tries to capture the real world will always be subject to compromise in a way that purely digital data isn't.
As for separate cameras... people just seem to prefer cameraphones. That's convergence for you. It might be down to lifestyle: I still use a separate camera if I want to take high quality pictures for ebay or wherever, but on unexpected occasions it's just so much handier to be able to use my phone as I have it with me all the time anyway. Very few people have ever carried a camera with them wherever they went, and a poorer quality cameraphone is better than no camera at all.
Ultimately none of this will matter because cameraphones will eventually be (or already are?) "good enough" for most people in most situations. Once that happens, only serious photographers will be bothered about cameraphone defects.
This crazy hunger after horsepower is happening in all sorts of fields such as home broadband connections. The BBC recently did an item about the ISP market in France where people are ordering speeds of up to 100 megs! Unless you're downloading vast quantities of high resolution video, there's really no need to go anywhere near that speed, but the ISPs explained that customers wanted it and to remain competitive they had to offer it.
Personally I still use 512kbps because it does everything I need it to including video and audio streaming. Any higher speed would be a complete waste of money for me because I've never experienced a situation where higher speed would be of any benefit.
