I'm not impressed with the device...nor the numbers.
neither am I, just saying apparently some misguided souls feel it useful.
Although I suspect it's more akin to the "usefulness" of an ipod- I mean, you can get any old MP3 player, but people seem to have it in their heads that the only MP3 player "worth getting" is the ipod. Although you have to hand it to apple, considering that the ipod requires custom software, only handles a few file types, and has a non-replacable battery AND still has a higher price tag then equivalent players that are better in all the useful senses of the word, the fact that they can keep the "cool" factor despite it's obvious shortcomings is nothing short of a testament to how it's not useful for it's function but rather for it's form. Much like a golden toilet.
Same is true of the iPhone, despite it's clear shortcomings and never-ending problems (the same sort of problems the early cellphone when you practically needed to drag trailer behind your car to go "mobile" that were resolved long ago by the more established and experienced cellphone companies) it's still managed to become "the" cellphone to have.
it's more a testament to the marketing zeal of Apple then their ability to create a quality product. I mean, come on- the first iMac didn't even have a floppy drive. This was 1998. You pretty much needed one. people say it "was ahead of it's time" maybe. Too bad they didn't create flash drives ahead of their time, as well.
