Way too few startups use price anchoring strategies when presenting their prices - the iPad intro is definitely not the first, but possibly the most well-executed anchoring I've ever seen. If your product is disruptive in the sense that it potentially can replace a more expensive existing solution, you should simply point out the math - the higher the original number, the better, as even the higher price points you've been thinking up for your product will seem small. Interestingly, anchoring can also work outside of mere price comparisons. That is, sometimes it's enough to just present high numbers to effectively prime customers towards higher price points. The most famous example is Kahnemann's classical experiment on using subjects' (obviously random) social security numbers for anchoring:

"...an audience is first asked to write the last two digits of their social security number and consider whether they would pay this number of dollars for items whose value they did not know, such as wine, chocolate and computer equipment. They were then asked to bid for these items, with the result that the audience members with higher two-digit numbers would submit bids that were between 60 percent and 120 percent higher than those with the lower social security numbers, which had become their anchor." http://en.wikipedia.org/wiki/Anchoring
