i have it downloaded, the only glitch i found (and if you are into chatrooms its a biggie) is that it will boot you every now and then when you log into a chatroom or if you are in a conference with users using older ym versions. other than that it is prolly the best IM service out there, and the free worldwide calling dosent hurt either although its pc to pc calling on the beta, still the voice clarity is better by far than anything out there
