For all kinds of subscriptions to mailings lists, newsletters and such, I still use my old @hotmail.com mail address, besides my Gmail and my @zzillezz.net addresses. I’ve noticed that Microsoft has started to deploy their new look to certain accounts, but mine hasn’t changed as of yet. From what I’ve seen, it’s an improvement. And it’s actually faster, less cluttered and easier to read. Just as they said it would be! And coming from Microsoft, that’s errr, weird.
