First deal post so please be gentle :)
Was just in my local Comet store and saw this 500 gig NAS drive reduced from £99.99 to £62.99. There was only one left and there was a sticker on the shelf saying that it had been reduced as the item has been discontinued.
The drive can be used with Twonky media server and stream media to the XBOX360 and PS3 very well indeed as well as being natively DLNA compliant, however this is a little flakey.
I paid more than this for the 320gig one I have.
Maybe this can help somebody.
