Yeah, I had a moment during the delete where I thought "But what if things change and I wish I still had them....."

But now that I log in with a single bnet account and there aren't any un-used account in my account list I'm pretty happy with it. If they'd been BC or Wrath upgraded, that would have been a whole different story, but vanilla wow accounts are small cookies to replace. Especially when they have nothing on them at all.
