I would have to agree.
I love mesh and am buying it, but it doesn't work for everything. While I'm used to changing my shape, most times my shape isn't even visible - the concept of alpha layer hides it. As a model I've spend long hours tuning my shape to make it the way I want.
I appreciate designers who make several sizes - but you would think a mesh outfit would adapt to a mesh avatar.
And the whole alpha bit is rather annoying especially if you have 2 mesh pieces worn.
There are some issues, but I think it will be a new part of what we wear, not a replacement. So far I'm having fun with it !
