Apple is telling Windows users to put off upgrading to Vista until it has a compatible version of its iTunes software ready, according to the BBC.

Apparently music and video purchased from the online store can fail to play. Other problems supposedly include poor animation and other media, contact and calendar synchronisation problems.

The announcement comes as Bill Gates added fuel to the fire by slating Apple's amusing 'get a Mac' ads. No news is bad news and, like every other Vista story, Gates has given Apple credence by commenting on OS X.

On a side note, type in Bill Gates vs. Steve Jobs into Google and you get a fascinating array of articles criticising Jobs for doing so little for charity, despite having a $4bn fortune. As a show-man I'm sure he could stir up hysteria about a charity in the same way he made Apple fan boys go crazy for iPhones... think iCharity.
