Some time ago, Microsoft had the same idea about dealing with having 
half an operating system.  Didn't work for them, not going to work 
here.  Overlays are building on sand, or trying to sweep the mess 
under the layer.  They can't fix what is fundamentally an incomplete

God forbid, they should tackle the fundamental issues that have been 
around for a long time.  Better to declare victory and move on, I 
guess.  Problem is if they couldn't solve the old ones what 
confidence should we have they can solve the new ones.  Especially 
when it is highly likely the new ones would not be much of a an issue 
if they had solved the old ones.

Stagnation is so dull.

Take care,
