Apart from two obvious differences (FW800 and internal bluetooth option) and a third in that the size of L3 is halved in the newer models, is there anything else that differentiates these models ? Also, reducing the L3, isn't that going backwards ? how much is that likely to reduce performance ? I am really not sure why I should be getting a new one: FW800 does not seem to be a big deal (well, it just is not and will not be for the foreseeable future); internal bluetooth, well one thing it does for sure is delaying shipment for weeks; and finally I bet, regardless of the impact, it is better to have a 2Mb L3 rather than 1Mb. Any thoughts ?
