In SquirrelMail's case it gives you access through the IMAP protocol to your email account. This means that you don't have to figure out how to setup someone else's stuff just to check your mail.
Any where there is a browser available. Wireless access (WAP/WML) is not on the drawing board at this time though.
It is doubtful that webmail will ever be a complete substitute for a regular email client. But hey, who knows? Anyway, If you ever were at a friend's house, on a trip, at home or work and away from your computer and wanted to check your mail you already know why. Because it is a huge hassle to set your mail up on their computer and then delete it again. SquirrelMail is designed to be a supplement to your normal email client.
SquirrelMail uses the IMAP protocol, info on it can be found here. The program also uses its own IMAP functions, not those built in to PHP4. This won't matter to anybody except those responsible for installing it, but trust us when we say they appreciate it.
