I've been thinking about acquiring windows 7 and I have a few questions.
1. Can I "Upgrade" and still keep all of my files, programs, games, music, ect.?
2. In Jan when I have to buy it, will it be cheaper than buying off the shelf?
3. Is it really that much better than vista?
1.) You can do an in-place upgrade from Vista.
To upgrade from XP, you will need to backup your files, clean install, then
reinstall your applications.
To upgrade from Windows 7 RC, your data will be backed up for you in a
WINDOWS.OLD folder.
2.) The Release Candidate will fully expire June 1, 2010.
You'll get two weeks' notice, and then beginning on March 1, 2010, your PC will start shutting down every two hours. So, you won't need to worry about purchasing until March, basically.
I doubt the prices will vary much between now and next year.
3.) Windows 7 is much "lighter" than Vista, but if your hardware can run Vista well, you probably won't notice a difference.
