Ive already given out all my invites, as Ive had gvoice for a while now, but Ive heard you can buy invites on ebay pretty cheap. I use gvoice for business and its amazing. The transcriptions are about 50/50, but they can account for accents, which I think is amazing. The only thing I dont like about gvoice on the droid, is that you can only use your gvoice number as your outbound caller ID if you are calling from your phonebook or contact list, you cannot just dial a number or else it uses your cell number for your caller ID...that sort of sucks.
