I vaguely remember an index for the number of earthmoving machines per capita for a given country. It was a really good indicator for productivity. It doesn't seem like industrial robots have the same level of correlation. At least not yet.
I'm in the accelerated testing group and I was moved from Mail to the new Outlook a couple of months ago. It's better than Mail for Windows in my subjective opinion, but it was a bit weird to switch just when Mail had gotten the last missing basic features, like signatures etc.
In e-commerce I've noticed that customers that request to be removed from the mailinglist and/or to have their info/account be deleted often forget about ever using the site. Then a few months later they order something and sign up for the newsletter again. When they receive their "first" newsletter they recognize the style and remember that they requested it to be cancelled, which leads to many angry emails and spam reports.
An order form with no pre-selected "join newsletter" option doesn't seem to mitigate this problem. The obvious soloution is to save the customer's email in the mailinglist as unsubscribed, but afaik that's not legal if they request an account deletion.
