Economically speaking, you’re probably better off getting Windows 7 Ultimate.
Windows XP will, like it or not, will soon enough go the way of Windows 95. Since it is now two releases behind and 11 years old, that argues that it will be sooner rather than later.
Although primarily a Linux user, i’ve had both Windows XP and Windows 7. Both have their strong points, and both have their less than commendable areas.
IMO, it is probably better to go with Windows 7 for longevity purposes.
Thanks, you agree with post #85
