I still prefer USB, much more widely adapted than TB.
I also love how MR and other Apple-fan sites completely downplay USB 3.0 and other "pc technologies".
Thunderbolt, which moves data at up to 10Gbps in both directions, appears mostly on Apple devices currently, but devices tend to be more expensive than their USB 3.0-compatible counterparts...
"tends to be more expensive"???? More like "ALWAYS MUCH MUCH more expensive." USB 3.0 external hard drives are about $12 more than their USB 2.0 counterparts...and are easily found in $100 external hard drives of 2TB and larger. And do 2.0-only drives even exist anymore? How much are TB drives? At least double...if not triple and quadruple the price of the USB 2.0 drives. Also, USB 3.0 and TB are designed for transferring large amounts of data...hundreds of gigs or more...so USB3 and TB are not used for mice, keyboards, and likely printers. They are going to concentrate on storage devices, and maybe as TB has tried, some kind of 1-plug-does-everthing thing.
A quick look at newegg.com shows 4 TB external drives for sale while 226 USB 3.0! And that's still years after both specs have been released. TB drives there start at 4TB (ok, cool...but how many consumers do you know need 4TB RAID configs for their external drive to save some music, pix, backups, etc?) and therefore start at $579...while USB 3.0 1TB drives start at $69, 2TB start at $109. We can't compare every single spec (mainly because TB starts so high in storage, price, and features) but how did the TB people expect to sell a product that most consumers don't need, can't afford, and are only for Macs? Sure, tell me the product is aimed at high-end, Mac-businesses, that NEED this kind of speed and what do you get? You get about 300 sales a year.
TB has been dying since the day it was released...mainly due to 1)insane costs, 2)extremely (and I mean extremely) limited number of devices (like 4) 3)Mac-only, 4)high-end Mac-only. It's been 2 years ago that TB was officially released and yet feels FAR longer than that due to all the hype in 2010 and 2009. TB may be adopted by some businesses that have high end Macs and have $2000+ to fork over to get higher speeds, but that's it. For the 99.99999% of the rest of the world, we'll use the USB 2.0 and 3.0 standard, that is so familiar with everyone and every single device on the planet. TB is and has been, dead.
