A
hosted email service makes a lot of sense particularly for small businesses. In this day and age, it makes no sense to maintain your own mailserver, spam protection and the works. Google's Apps for your domain, MS Office Live are both similar to Yahoo's small business offerings. All three save businesses the headache of managing their email. The best part is that its possible to pop your email when you use these services. This means that if you love MS Outlook (or any other mail client) but hate Gmail (or Yahoo Mail, Hotmail interface) , you are still in good shape! Hopefully, someday "everything" will be free provided there is still money in ads! :-)
