I use hotmail.

I've heard of some better ones alot, but I just use Hotmail because its older and very trusted.

And I've also had my hotmail account since I was 5 (yarly, Lol)

I'm using GMail extensively for all my Personal Mails. I also have my professional mail setup on Google Apps.

Other than GMail I use Live Mail occasionally and Yahoo! Mail very rarely

I use Yahoo. I have tried almost all other big name Email providers, but none of them can compare to how good yahoo is. I don't know why, but it seems to look a little better, especially the new version.

Gmail all the way, ill give you the reasons why a gmail account is better (IMHO) than windows live mail/hotmail/whatever those crazy lads at microsoft are calling it now.

Gmail has free pop retrieval (no need to upgrade and PAY for this) Free spam detection, not to mention all the things you can get, orkut, blogspot, google docs, the list goes on. Not to menion the fact lots of people use it as an FTP server (as in upload to gmail and access it from another computer)

Google basically has the monopoly on the internet. When something's name becomes a verb you know its big "google it" i think that for personal use (other than porn) Myspace, facebook, google and wikipedia are probably the most well known and most visited sites.
