That's a very realistic "wish list" you have there and I'm sure many of the most current HTC/Motorola/Apple handsets are already matching them specs already.

Have you looked into what many other companies are selling today? You may find what you are looking for with them?

However, if you insist on having a Nokia badge on the phone of your dreams, then you might be better posting this on one of the many Nokia branded websites and not Maemo.
