Windows 7 Family Pack now available in 46 countries
Windows 7 Family Pack allows you to upgrade three PCs to Windows 7 Home Premium at a heavily discounted price. In the US, this is $149.99. The normal price of upgrading just one PC to Home Premium is $119.99, which makes this a very compelling offer -- netting you a total savings of $209.98.
... In the U.S., anyway. Pricing for the Family Pack in the other countries has not been announced, and that's because it will probably vary in each country. It will still be significantly cheaper than purchasing three full-price Home Premium upgrades though, and it looks like supplies are limited -- so if you want it, you need to hurry.
