That's a bummer about the battery getting sucked down so fast.
If all the software you use is already installed on it, then you'll probably be okay. All my data transfered over well. It was the software I use that I had trouble with. Some of the software that came with the scanner, in particular.
Will you have to add more software to it? Sometimes it's hard to tell if it will be compatible. Usually, it will say if it's Vista compatible, but I guess sometimes it also needs to be 64-bit compatible. I'm not sure if that refers to an addressing/register size or what
Or why it should make some software crap out
But it's darn frustrating when it does!
