Is this going to be exactly what Windows 7 is going to be when it comes out? Will the RC last forever or will you not be able to use it once June 7th or whatever of 2010 hits. Is that when people can just stop downloading it or is that when you can't use it anymore? Also, if this is like the real Windows 7, who is going to want to purchase it, when they can just get a copy for free. There has to be a catch here, can someone shed some light for me? Thanks!
