I got 2 "newer" computers when we had to upgrade to the 64 bit system. Fortunately, I have an IT guy who took care of it all, while I sat there and watched for 5 hours.

While I'm a tax lady, not a tech lady, it seemed to me that Intuit does not make it an easy process to switch machines. Once you download the software, that's all you have. All the other data, Client Files, EIN Database etc. are all in separate locations with instructions for each. Only the EFIN info is carried to the Set Up/Options, so you have to reenter the rest for each year. There are shortcuts, I'm sure, but I didn't know any and, of course, the IRS was ready to open the filing season.
