I would vote for Gmail also, only because it is much simpler, less cluttered, and more user friendly than hotmail. I hate the hotmail site. It's such a mess, and really slow when not using IE.
When using IE it works just fine, but in both of the other browsers I use, it is really slow to "adapt" everything to fit.
I use it for skydrive ( the small bit that i've used it so far anyway) and that's about it.
