The article is good but it does not tell me much of the ability of LM2 to handle large, complex vector drawings (and I'm not talking at all about scripting). I personally dislike Flash because of how weird and counter-intuitive it is; on the other hand, I think that Flash is much more powerful than LM when it comes to creating sites that have lots of vectors and are created for large screens, at least when compared to version 1 of the Adobe product. In fact, my first impression of LM was that it was probably only meant to create small swf banners and such.
I'd love to upgrade but not until I hear that it can handle large, complex vector files like Flash can.
