Overall
iPhone 3GS : The iPhone is a blockbuster phone that has won many hearts. After some of refinements the iPhone 3GS model seems to remove all the flaws that it had in the previous models. Now it stands as an irresistible champion.
Blackberry Tour: Blackberry is always the first choice for the business users and the Blackberry Bold is the best BlackBerry phone ever made. It is also an unquestionable choice for a corporate person.
Nokia N900: The Nokia N900 is currently the best smartphone that Nokia has ever produced and I'll call it a smartphone even if the company brands it as an "Internet tablet with phone functions". As a voice device, the Nokia N900 does very well, and as a communication tool, it is very good too. With Maemo, Nokia's smartphone future seems a lot brighter than it is with Symbian OS, but despite the obvious potential, the number (and quality) of applications is still uncertain right now.
Conclusion: At the end of the day all of the third phones are tough competitors and it is hard to decide which one is the best. None of the phones can be neglected for their shortcomings because they have some features that outdoes others in some respects. But, the N900 faces stiff competition from the iPhone 3GS and the Blackberry Tour, just to name the obvious ones. It might have a "features" advantage, which is great, but I wonder if "technical coolness" will convert into actual sales. My personal take is that the 3GS will still be the most desired phone, with the Blackberry fast becoming second in line. If Nokia wants to create a great smartphone eco-system, it needs to have a strong user base (in that space), and to achieve that, it needs sexier phone designs, there's no way around it. At last, I wish Nokia will have good sales.
