I also bought an N900 before christmas, and the microphone stopped working the first day. The retailer replaced the phone but within one week the ear peice stopped working. I agree with forum member that the Nokia Claim: "It is an Internet Tablet Device with Phone Functionality added", but it is not a very good Internet device as many websites are not rendered or function properly with it and the added phone functionality was very poorly implemented. In my opinion, after owning every model of the Communicator, and N95, N96,97 and 5800, the N900 the worst phone I have ever owned. It has become a common practice for Nokia to pass quality control testing to customers who are paying full retail prices for their products. How can a company with so much phone manufacturing experience produce a device with phone functionaliy that doesn't address the primary, and basic functionality of a phone, simply for 2 parties to speak and hear one another. Afterall it is 2010 not 1980.
