We haven't instantly forgotten how Microsoft handles Skydrive, have we?: http://news.ycombinator.com/item?id=4265086 I think I'll pass on putting my email through their systems. Although I have to admit this looks way better than GMail. I hope this inspires Google to do something about their interface design.
As a big Android/Google fan, I can't say they are exactly innocent when it comes to the sort of thing Microsoft was called out for with Skydrive. When Google+ first came out quite a lot of people lost their "Google lives" (including their gmail accounts they had been using for years) when Google banned them for being under 13 or using a pseudonym.
I think the issue got resolved because he was lucky enough to be a nerd which a blog that got picked up by HN/Techmeme etc. and then someone from Google personally fixed the problem.
Most users would have been hosed. It also doesn't help that Google has no "real" customer support other than forums. As a user it would be extremely uncomfortable to lose your Google life and have no phone number to call.
At least you can call Microsoft. Whether they can do anything about it is a different story but it at least will escalate easier, or at least I would imagine
