Hate to say it but I need to buy a Windows Machine. My main concern is that everything is Win 8 (not easy to find a Win 7 machine), which I hear stinks. Can I still get a Win 7 Machine? I hear Microsoft wants all the new software designed for Win 8. Those tiles will drive me nuts! Second concern is brand? Any recommendations? I hear Asus is okay. So should I buy a PC with Win 7 or Win 8?
