why not wait for new devices and save your money

surely the n900 will do the job untill the 4th gen iphone or the latest symbian3 device is released

and your question isnt really great , as another user pointed out , you havent even said what you'll be using the device for etc

surely it cant be that hard to sit down think about what you want and read some reviews mate and it would be alot better then being led by the blind as we dont even know what youll do with the device
