Some comparisons really don't work, but are presented as if they are spot-on. Here's one from CNN's "Smartest People in Tech" that I found amusing, from #2 CEO Jeff Bezos' writeup (which comes after #1 CEO, Steve Jobs).
...virtually every iPad review compares Steve Jobs' tablet to Bezos' device.
Well yes of course, since readers aren't going to know of any of the few other touchpad devices out there (not touch phones, but touch pads). Although why you'd compare the two, when the Kindle does only one thing (and will probably stay that way) and the iPad... well, as the advertisement goes, there's an app for that, it's not a great comparison outside of the form factor and that the two devices are contemporaries.
