My trial period for ATI 10 Home is almost up and I've determined that it's the better product over Norton Ghost 10. However I've seen through Newegg that version 9 is available more than half off of the version 10 product. From what I've been able to gather through Acronis' web site, the only difference is that version 10 support Windows Vista. I'm still going to stay with Windows XP for at least the next couple of years. Are there any other differences between version 9 and 10 that I should know about, or would purchasing version 9 be sufficient enough? TIA.
