The Windows 7 Professional Upgrade will not be available until October 22, 2009. However, if you want to pre-order now, Amazon has a great deal, which saves you a hundred dollars.
Amazon even gives a price guarantee:
if the Amazon price decreases between your order time and the end of the day of the release date, you’ll receive the lowest price.
There is a limit of three (3) per customer, and is an excellent deal. At least, it provides some top-end insurance. The price may be lower, but it can’t go any higher than this if you order now.
There is a Windows 7 Upgrade Advisor to see if your system can handle Windows 7. A small download is required in order to make use of this resource.
And finally, there is this stated caution on the Amazon page:
“We recommend that you experience Windows 7 on a new PC. While we don’t recommend it, you can opt to upgrade your current PC from Windows XP or another operating system to Windows 7…”
In this economy, there may not be the extra funds to go out and buy a “new PC,” as suggested. The upgrade may be the viable economic route to go — but do your homework. It seems that a hundred dollars (less a penny and with free shipping) is an economical way to have access to this new operating system.
