New Computer Struggles

I have been attempting to make the transition to a new, much faster computer. Although it's speed is fantastic, the fact that it has Windows 7 is not. I have never had such trouble in my life. My laser printer, keyboard, mouse, all are incompatible and my inkjet doesn't work with Photoshop the same. I have returned the computer to its maker and am asking to have Windows XP installed instead. How can a billion-dollar company sell such a buggy product??? If you go to the Windows website there are apparently thousands of others with the same problems. When all of my Adobe CS4 Design programs stopped working entirely yeaterday I said, "enough is enough!". Microsoft, you have a lot of explaining to do......
