Should I jump on the bandwagon and download this beta release like everyone else? I thought people didn't want to download the early alpha releases of SP2 because it contain several bugs... what has changed since then?

I downloaded it (Beta Member) but MSN Premium gets screwed up so I uninstalled it and will wait until another build comes along. 3 & 4 options requires you to get a new product key?! Also, when setup begins: 180 days left .....
