Microsoft just laid out the Windows 7 pricing grid for us, and here's the big takeaway: Vista and XP users will need to pony up $119.99 or $199.99 on October 22 to score their Windows 7 Home Premium or Professional upgrade, and those of you who want a full retail disc will need to roll up with $199.99 or $299.99, respectively. It's not quite that simple, though: starting tomorrow, June 26, you'll be able to pre-order upgrades at much cheaper prices -- $49.99 for Home Premium and $99.99 for Professional, just as we'd heard -- but pre-orders will be strictly limited in number and are expected to sell out quickly.
