OK, first the good: This is a fun toy, an entertaining piece of Whovian kitch. It's got the flashing light; it's got the proverbial wheezing, groaning sound; it looks really cool sitting there on your desk.
Unfortunately, it's a bit too much like the "real" TARDIS when it comes to reliability. Sometimes it works fine, but other times the signals from my peripherals are apparently arriving on Mars, or in the Middle Ages, or somewhere, because they're certainly not getting through to my computer. I eventually had to unhook my scanner from it, because it just wasn't staying powered up and connected for more than a few seconds at a time (even though the printer, connected to a different port, was fine).
Bottom line: If you're as big a Who geek as I am, and you mainly want a toy that goes "vwoop, vwoop" sitting next to your computer, it might be worth it. But I wouldn't choose this thing if what you really need is a USB hub you can rely on.
(By the way, I feel a bit bad saying this in an Amazon review, but ThinkGeek has it considerably cheaper.)
