mjasay writes "I stumbled across this fascinating Microsoft tutorial entitled "How to Justify a Desktop Upgrade." It's an attempt to coach IT professionals on how to sell Windows desktop upgrades internally. Apparently the value of Vista is not readily apparent, requiring detailed instructions on how to connive and cajole into an upgrade from XP. The most intriguing thing about the tutorial is its implicit rejection of Microsoft's older technology. Just a few years ago Microsoft was pitching the world on how secure and cool XP was. Now it's telling us largely the opposite, implying that XP is a security threat, costs too much to run, and so on. With Microsoft marketing against itself, perhaps the Mac and Linux camps can simply wait for Microsoft to self-destruct?"
