Been doing some reading, are they as good as they sound? Anyone have any predictions when they will start dropping in price and why exactly are they so expensive? I'm looking at one 250GB for 360 quid on Ebuyer. Sounds pretty attractive since I use my hardware under demanding conditions (i.e. freezing temperatures, rough travel, high humidity). But 360 quid isn't exactly small change, and in comparison, the 500GB WD Blue is only 50 quid. Opinions?
