I am a major fan, however I am not completely obsessed with Tamas. I see them as a hobby mostly and not as real pets. I can attest to this with my real pet, a miniature dachshund.
However, I am still highly anticipating the V4.5, and am prepared to start my V4 back up so it has something to connect to. I'm just running my V3 until the V4.5 falls into my hands, so to speak.
