I never used Blackberry until I got one for work and the most used feature is: BBM, it's so fast and efficient. Most times people working with each other know what's going on so a To: and Subject: then type a message in the body then Send seems so stuffy in comparison. Most times people end up putting the entire message in the subject line, like a pseudo-BBM message. Now the trend seems to be BB is dead so iPhones are popping up for managers and Android for others. It's stifled the back and forth banter of BBM messaging, people who had a BB but switched just seem to disappear from group discussions due to the awkwardness of e-mail.
