Which program do you prefer? I've only used PM, but when I went to buy it from Amazon, I saw that some people bought Acronis instead (never heard of it). So is Acronis a better product... or is there an even better third option? We're getting ready to purchase one of these titles for work, so I need to decide which one to grab. It has to be able to handle NTFS partitions (which I'm sure they all do by now)... being able to use it with *nix would be cool, but isn't a necessity.
