No, but a product can have the most features of any product in the world.
But.. it still has to find enough of a niche market to sell to, to become profitable, and you have to make your product marketable, and at a good price.
It's hella expensive! By your own recognition, (that's if you have the hardware)
The cable is 50 bucks, and a 2TB hdd is $500, I presume that's american, in which case I would talk NZD, so $100 cable, and $900 dollar HDD.
Compared to a USB3 2TB HD for $150 NZD, which requires no special hardware (as USB 3.0 is increasingly built into most new computers/desktops)
And let's be honest, if your average joe bloggs with his USB3 HDD can copy over a 1.4GB movie at 150mB/s (at this stage) why would he honestly fork out $1000 for the ability to copy it over a few milliseconds faster?
It's incredibly proprietary which means it will be limited to the devices it's built into, or expensive add-on cards, which unlike USB is built into everything from phones to camcorders and laptops and desktops.
Also if Apple's track record is anything to go by, there will be very little backwards compatability between generations of device. Meaning your 50 dollar cable, and 900 dollar hdd may be a paperweight if it doesn't work in your Macbook 2 years later.
I suppose that will come in time, but history is littered with superior products that failed to inferior ones simply due to bad marketing and not big enough niche.
It's a freaking great idea, and STUPENDOUSLY fast, but I reckon it's come at the wrong time, or at least, will take a wee while before anyone could say it's the next firewire.
