Stephen Fry has let rip another tech-related tirade on Twitter, this time with PCs on the receiving end of the Mac-loving entertainer's bile.

Following his recent attack of the BlackBerry Storm, it seems Fry has struggled to get to grips with Vista, and a high-end Sony Vaio laptop, with one Tweet reading: "I hate Vista so much I want to cry. Bought a Vaio. The most useless $4k ever spent".

Apparently purchased as Fry needed a machine running Vista "so that I can review things", the set-up of the new device did not go well with Fry experiencing issues trying to network the device.

"I just want ONE A**ING PC that isn't complete SHIT", ranted Fry, and then: "Too late. It's going out the window. I can't put up with this sort of arse".

Later messages on the micro-blogging service from Fry state that he's calmed down and that "Vista and PCs are so crap it's funny", with the most recent post reading, "The Vista devil spoke thru me and it wasn't pretty".
