7048 x64 is already leaked & available. I'll await the x86 version. This is touted as a milestone build, not sure what changes will be in it, but hoping for a resolution of the dual path tv tuner problem thus far seen in every beta release which quite honestly is all that's stopping me using it full time as an htpc build.
FWIW, I've been running build 7000 as my full time main office pc for a month now & it works pretty good. The one issue from an office productivity point of view is with printng, I print an excel form to fax & am used to clicking, print>fax & off we go. Now with 7, it inserts multiple page breaks that can't be removed, so as a workaround, I print the page to pdf, then print that to fax. Otherwise, it's as smooth as silk.
