I managed to get one of these a couple of days ago from my local PC World for a friend. I got myself the Toshiba 320 gb drive last week, but as that deal has expired this looks like a good alternative. The PC World usual selling price is £82.20, checking around on a few other sites this is still about £10-20 cheaper than they're selling it for and you can reserve and collect it yourself... which is good as I am impatient :-)
The offer applies to the Red and White drives (I assume Black and Blue plastic costs more to produce :-))... and in store only.
Powered off 1 USB 2.0 input, case seems sturdy enough, quite a handy piece of kit.
Not sure how this stacks up from a specification perspective against the Toshiba or the iOmega alternatives posted recently.. but I thought it was a good deal at the price.
... and it's less than £1 more expensive than the 250 gb they are selling.
First post, but hope that sorts someone out.
