Getting a new computer at least for me is always a treat.   No more slowness, no more errors. You are already to go except all your info is still on the dinasour. If you do not have much data then you can always manually copy it over to a flash drive or over the network and then move it to were you want on the new computer.
Check out this nice little guide called data from one computer to another.

If you just need a few files transferred over then it’s no big deal.   You can use a USB device.   If you want your custom settings like bookmarks and the like then the above is a great site to check out for a hands on how to guide.  We also found this other PC to PC file transfer guide on the same site that has even more info.

If you are looking for more of a fresh start then I do recommend you don’t transfer over any personal settings besides your e-mail account or bookmarks. If your like me and need to transfer over programs as well then their is only one specialized file transfer software.

Of course you can always use the Easy transfer software that comes with XP and vista. While the software is far from perfect it can and does get the job done in the long run.  Often times you may find it a little frustrating and it may take a few attempts to get the information you want.  We should also mention that before you do any data migration from your old computer to the new one you should always try and install the software first on the new computer.  This will help to make sure the data ports over correct.  Outlook is a big one for many business owners.
You can always manually copy and paste info over to your new computer as well.    If you have very little documents and no other info then this is the best way to go as it will only take you a few minutes to burn a CD or network the computers to view each other and then copy it over.
