GMAIL IS OBVIOUSLY the best in the universe - its easier to integrate, you can transfer from your old account plus you can sign up for google apps where you get something like yourname@whatYOUwanthere.com. There is chat already on the page with your contacts, plus if you have slow connections you can you can have a basic html view, unlike fancy ones like live mail, aol and yahoo, which work ridiculously slow. Inbox.com offers 5GB only for United States, Canada and United Kingdom residents, with only 2GB for other locations, which wont work for me because I live in the Caribbean. Gmail, now, on the other hand, is almost 3GB (and counting) for any part of the world. Gmail's size (for each person) increases by 8 bytes every second. You can specially mark some with stars and do all the usual stuff as with any other. plus you can view info, invite people and so on. There is a calendar and document reader, your own avatar, photo uploads, and , unlike yahoo, which wastes time attaching files, the file attaches itself while you type. that is cool. so, don't take my word for it, you check it out!
