Yep, I'm here.
After people talked about 'moulding marks' on the Givi, I had to take a look and sure enough, there appears to be some sort of fine bubbling in the plastic that I hadn't noticed before. I had to look for it, and it's only noticable around sharp bends where the lensing effects are extreme anyway, so I don't find that to be a problem. If I can, I'll take some pictures and add them to my site.
I don't regret getting the screen. Riding is far more pleasurable now than it was originally. Plus, it's available NOW, which is a big plus! However, once the Clearview comes out for the 400, I'll have to see what people think and would consider an upgrade if it's substantially better.
