Addicted to BB!

Ever since I installed MSN Live messenger on my blackberry, I have become even more obsessed with BB. I can now chat via three different chat programs (blackberry, gTalk, MSN) and also update my status on Facebook. I simply cannot put it down when I am in transit. Even now when I have no emails to check, no one to chat with (dinner time), no status to update (just riding the bus home), I'm still blogging via BB. I think it would be quite hard for me to decide whether I could migrate to iPhone...
