Hey, I am needing to sort out a backup solution for my laptop and my wifes. My laptop is a Macbook Pro (10.5.4), but my wife's is a Win XP laptop. I have been looking at either the 500GB Time Capsule, or the 500GB Western Digital Mybook World. Both devices will connect onto my existing network. Since I am using both Mac OS and Win XP, what would be the best solution? I don't care that much about the Time Capsule having an N router in it (it is a bonus, but backup is the main concern). The thing that is making me think twice is that the Time Capsule is about double the price of the Mybook World. Has anyone had experience with how either of those backup devices work in both Mac OS and Win XP at the same time? What XP software do you use for the backup? Thanks.
