Everyone is free to have an opinion, no need to be sorry that you disagree.
From my point of view if I wasn't on the beta team I would absolutely buy a fully assembled version. The reason being that I believe in the hardware and would do whatever I could to obtain one.
Your points are valid, and I applaud you for putting them in a well written and cogent post. Lately there have been some threads that have gotten out of hand with demands and requests.
It really is good to see so much interest in the project and the desire for people to obtain the XLD. As you can see the decision was made to offer a fully built unit as well as a set of boards, so you will absolutely be able to obtain those and build your own from scratch. You will just have to do some of the work locating the BOM (which to be fair a lot of the beta group did too).
I wish you the best of luck with the build and I'll be looking forward to seeing some pictures when you get it fired up.
