Ordered Windows 7, 3 licence Family Pack Home Premium today from Staples, free next day delivery apparently, but will probably not get to do any installs before the weekend. A little concerned about the way some sites have been advertising Windows 7, whilst the price is the same, they advertise separate 32 & 64bit versions? It was my understanding that all versions were on each DVD and it was just a matter of which you chose to install, paying a fee to upgrade to Pro or Ultimate? Not too fussed, will go with 32bit if necessary, but was certainly planning on putting the 64bit version on the laptop, seeing if any problems cropped up and making a decision about the other two desktops once I had got it bedded in on the laptop.
