Should Vista users get a Windows 7 upgrade for $29?

So, Mac OS X 10.5 "Leopard" users will be able to upgrade to 10.6 "Snow Leopard" for $29 once it's released in September. Should Microsoft give the same deal to Vista users?

So, let me get this right:

• Leopard --> Snow Leopard - $29
• Vista Home Basic upgrade - $99.95
• Vista Home Premium upgrade - $129.95
• Vista Ultimate upgrade - $219.95
• Vista Business upgrade - $199.95

Now, we don't know how much Windows 7 upgrades will retail for, but if it's genuine then the leaked Best Buy memo gives us a clue:

• Windows 7 Home Premium - $49.99
• Windows 7 Professional - $99.99

According to the memo, these prices will only be available for 16 days through July 11, so following that we can expect the price to go up.

Apple's decision to allow Leopard users to upgrade for $29 (the upgrades usually cost $129) suddenly makes Microsoft seem expensive. If nothing else, it's an interesting counter to Microsoft's "Laptop Hunter" ads. "Laptop Hunter" ads try to portray Apple as the expensive option, a ploy that seems to be successful. This slashing of the upgrade cost should help Apple counter Microsoft, and since Microsoft only makes money from the sale of the OS and not the hardware, Microsoft could be both vulnerable to this ploy and unable to offer such deep discounts to counter it.

Personally, I think that OS upgrades are too expensive for Microsoft users. Apple's $29 upgrade for loyal users (those who have the previous version) is a step in the right direction and I hope that Microsoft follows suit.
