some people make a living with that stuff 
i'm not saying that is coming substitute the 744 , but ....
if you plan on making a living than I would never even look into the tracker.
There are better options that you should be using. For one putting the house on cutting edge tech that has not even had a week to test in the field is ludicrous.
All it will cause is lost of money and customers imo if you plan on using it to make money right away and not wait for the unit to get tested thoroughly in the field.
1- i like your name :-) , since I'm a Guinness fun 2
2 - make a living with micro tracker for me - is to have another tool that can bring few pints .i never intended to make the micro track be my main recorder ,i have few better.
3 about testing ,the 99 % of people who lark in that forum cant test the recorder for my applications - we are just not use it in the same way , so if i wont or not i have to do tests or wait for people from my industry to do it for me , what can take adages since these dont like changes and the penetration and feed back very slow .
the reason i sit here and reed revues is to decide if i wont to check it at all , the mt will be here about a week from now , so it better be prepared for what to look for .
