This isn’t even a beta so if it breaks..burps..acts up..etc etc this is not the completed product.  The core is basically done which is why developers are getting this.  ECC’s testing of this begins immediately after I finish downloading the file.  Watch this space for ongoing updates.  I am going to install this on my core solo 1.6 ghz 2 gig ram laptop.  If it runs ok on that it’ll run on anything that currently can run Vista.
