I like that it allows me to quickly send email attachments as well as documents via fax without having to print them out first. It's also fast compared with other services in this space (i.e., Google Voice). The price can be prohibitively expensive at times. Also, sometimes things get stuck behind an "incoming call" screen; you have to close multiple tabs before sending your message so there are occasional delays. For those who use Gmail often and need quick access to their emails/documentsβ¦
