The improvement on collections with regard to functionality and speed, is one that I didn't have in my 'VB6 desires list' as I didn't know I needed it at the time I wrote it. I do now use collections in one of my utilities and I've noticed them to be slow, so any improvement will certainly be a benefit.

I once owned a .co.uk domain name, the named equivalent of the .com version of one of the big corporations, they hadn't snapped it up when it was available. I thought I was being clever pointing it to a sub domain on one of own sites that had some equivalent offering. I received a "cease and desist" letter from them. Very shortly afterwards, I did both cease and desist what I was doing.
