Just letting you guys know that after a long delibaration I decided to go with the 75S upgrade.
It took Leaf just 24 hours to upgrade it an send it back to me next day via UPS. Bravo.
First impressions are very positive. It is definately much faster. Also thethered to my MacBook the images are poping up about twice as fast on a screen. It came back with two new fire wire cables, the newer type B which is the 800 I believe. The actuation meter reads 000 which is also nice.
The case has the Aptus75S name on it even thought it is still the same housing. It also came with new software CD 10.044. My colors seem a bit off from what I am used to but with a few twicks I am back to where I want to be. Overall I am pleased.
Glad to hear this as I've been on the fence about whether to upgrade. Guess I'll send it in when Leaf calls...
