I've come to realize that an array of friends and family use all sorts of messaging service. This is becoming increasingly important considering soon i'll be packing up and moving to Japan for 6 months; where it'll be important to keep in contact with family. Skype: I enjoy Skype, considering for a low monthly fee it allows me to make free calls. Something that'll come in handy when i'm abroad, needing to make local calls and even free Skype to Skype calls. Currently, only my best friend has Skype...and uncle, lol, but hardly keep in touch with him. iChat: I enjoy this program, though currently only my sister logs on. She's also the only other family member that has a Mac as well. We enjoy sharing files, but more-so sharing each others screen. This has allowed us to get actual school work done, considering she's in New York and i'm in Cali...and soon to be Japan. & though we haven't done this, I know we can both sit down on different ended Macs and watch the same iTunes movie at the same time. FaceTime: I'll be first to say that I hate the quality of FaceTime. Skype and even Gmail's Google Talk have incredibly better video quality...but FaceTime seems to be the popular choice here, considering both my mom and dad just got iPhones, alongside with my sister. Also, another buddy has a Mac and we've FaceTimed a bit too. AIM: I haven't used the AIM app since getting a Mac back in 2006, but I still use my AIM SN, which is connected to my Google Talk and iChat as well... ..I know there are others but really these are the ones that seems most prevalent. Just wondering about you guys.
