E-mail Platforms

I currently use Hot-mail as my main e-mail. I have been thinking about changing over to google though. trying to integrate all my accounts into one main provider. Google mail has many features that are not provided by hotmail, although many features are the same. Such as a spam filter. A feature that I like is the search method with google mail. this allows you to search through your messages to find a particular message without scrolling around the inbox. The particular storage size of google is 4GB now far exceeding hotmails. Google also offers purchasable storage; as does hotmail. My main reason for wanting to change is that I already have a google account and I would like to be with all one provider. Eventually in the future I would like to use Outlook, maybe when i can afford to pay for it. That day might come when I own a business if my own and many features that outlook has would fit the needs of that.
