From what I am reading, if you can work in XP then it will be a lot like XP just better.
windowdog, I hesitate to say that Windows 7 is a lot like Windows XP. If a user has skipped the Vista generation and is going from XP to 7, then there will be some fundamental changes to get used to. However, Murrar, it is still Windows and it's a tremendously user friendly operating system in my opinion. If you have an aptitude for learning, especially with a computer, then you won't have too many problems getting acclimated to Win7. And, as always, if you have problems you know you can come here and get help.
Best of luck to you!
