I have been hearing so much about SIP-VoIP for a few days now and I am totally convinced on getting it....but the mic that touchmods.net makes is $45 and to me that is a hefty price for something that can only be used via WiFi, and usually if I am in a WiFi location, I have a phone with me. I keep hearing, "Oh well in the future there will be more features and stuff" and I just don't know. I can easily afford the mic, no problem, but I could use the $45 towards something else if it isn't worth it. Help? Advice? Bitter.
