I've used it a few times and was moderately impressed.. IM works great. Webmail is alright, but it gets the job done. Only problem I had is I was using it to connect to an IMAP account. Even after the flight was over when I would log into my account and noticed that messages were shown as being "read" even though they were new messages to me.. I found out that the webmail client was still connecting and getting the emails from my account.. so I changed the password and it stopped.. that was kinda weird though I thought.. and something CO/Verizon should address.. I don't want my emails floating around out there..
