1) "Oh, I wouldn't need any of that. I run Linux!!!" *motorcycle-noises* Then hang up.
2) As soon as they utter the words "tech-support", say: "Finally! I've been waiting for you guys to call back forever!", then channel the tech-support caller from hell and make them talk you through EVERYTHING (If you have time to kill, start with "So how do I open these Boxes?"). When you have run out of ideas for stalling and you are finally about to start downloading their software, make up some excuse (ideally one they can hear, like a doorbell or a dog barking to be let out), thank them profusely for helping you and being so patient, then hang up.
FT: All in all, this inlay is not taking as long as I thought it would.
The ones I like to troll are the ones who open with "Hello, this is [name] from [company]. How are you today?" Seriously? They're asking how I'm doing? They've never met me, and they're chatting to me like I'm an old mate. So my usual response is to concoct some heart-wrenching, and incredibly long-winded tale of woe, and never give the person calling a chance to speak. See how long it takes them to hang up.
