Although initial reviews have concluded that it’s far from perfect, today marks the first day of availability of the Nokia N900 in the United States. Available through Nokia’s flagship stores in Chicago and New York City for $649 (as well as at nokiausa.com), the N900 has also been spotted on various online shops such as Amazon for a little over $500. At that price it’s all very tempting — especially if you’re a die hard Nseries fan that wants to get a glimpse of the future with this Maemo 5 business– but that’s a decision you’re going to have to make on your own.
