Ive got the the 320 gb version. v good for what they are. just plug them into the scart on your TV, switch the AV, and you get a scrollable menu with your files on it.
Pros: Lifesaver when on holidays for the kids in the mornings. Configurable password protected folder, only viewable after password entered via remote.
Cons: I know 3 people who got the 320gb version and all have the same complaint which is the fan is noisy to the point of real annoyance. I believe you can remove the fan but that probably has its own implications long term.
If its only for home use, Id suggest going for one of the products.
