I looked in the forums but saw nothing about the blazer 4..how is it in speed and visually?what's different between 3.0 and 4.0?also do 3rd party web browsers(xiino , webveiwer..etc) work well/at all with the t650?if so, how much better does xiino look on the t650 vs. The t600?i'm a Wacky Web Wizard and this would be the "nail in the coffin" for me getting a t650..please let me know..!!!
