Christiaan, Here is a question, in your recent comment in regards to Ozzie's existing tree comment. Could you use numbers to create data in the field and import it to the existing tree tool. If so how? This would be huge for me and will be playing with it to test. please advise if you have had experience on this. As for the ipad app I am all for it. It would be an incredible resource in the field (I believe for all). I remember when I got the iphone thinking just a cool toy, now it is an integral part of my business and could not imagine working without it, I believe the ipad would be the same. VW should move forward not stand still. technology moves to fast. If other do not like or need the ability oh well, to each there own. I bought designer because I wanted Architect features. I have no use for Spotlight or Machine Design. this dose not mean that I am upset that these exist, or that I had to buy them, I just work on.
