I've read most of the thread so far, and I do a lot of what people have already posted.

I text a lot more than I talk on my cell phone. I don't like talking on the phone to a lot of people (there are a few exceptions however). This is because i did phone technical support for around 6 years -- so, 5 days a week, 8.5 hour days of nothing but talk-talk-talk to customers, call after call. It kind of threw me off wanting to talk on the phone a lot on my personal time, even now *lol*

I text message with my boyfriend throughout the day when hes at work - because he does technical support as well, i can send him quick messages and get quick messages back without inturrupting him doing his job. I also text him from moms farm on the weekends -- again, long distance costs money, but the text messages are free regardless of where I am. Makes it a lot cheaper when all i want to do is send the "thinking of you" message, and get my "kisses" in return

I also chat mostly with people through MSN - make plans, generally chat, etc. since you can maintain many conversations at once. I've even got my parents on MSN - since they like to call me at work at the most inopportune times, it gives them a chance to send me messages knowing that i'll get back to them when I can
