dated hardware? huh? N900 has pretty much the latest TI stuff there is, i think they have a little faster cortex A8 but as far as i know nobody is using them yet in a phone not to mention the cortex A9 (which is nothing more as fas as i know a dual or more core A8)
you seem to look at the mhz but the snapdragon is a totally different beast as the cortex A8 so they are not comparable by looking at there mhz numbers

als 80% Global share by rim and apple?? you must be kidding, global is usa market i guess? BB isnt really great over here and apple does it better but i know a lot more people with S60 and or Maemo then bb/apple
