If it's anything like the original models, the advice is STEER WELL CLEAR. Hopeless pile of junk, these. I had a 512MB MyBook World Edition. I bought it as it had a Linux distrib running it, and was fairly easy to hack, plenty of online instructions available. However, the hardware it ran on wasn't just mediocre, it was terrible. Not only did it have a permanently speed-crippled NIC (contrary to the marketing blurb touting its gigabit interface), but it had some hardware problem whereby the connection would frequently drop and need hard rebooting after trying to stream even modest amounts of data (few hundred MB). These problems were well documented and widely reported in the relevant forums.
