Slim Smartphone: Blackberry 7130g. It is good to see companies like Research in Motion (RIM) going from the PDA market to the smartphone market. This is a very good thing for me too :) I never liked PDAs because they are too bulky. I am more of a one hand phone kind of guy :P
It is good for my resarch too! I am doing my DIT on smart phones. So, RIM is a welcome addition to the mix.
