I have used windows for all my life, I want to switch to mac, the Penryn Macbook Pro is my choice, but I also need to have windows on my mbp. After talked to a technician at a computer store, he told me that using windows on mac is a pain in the ass, he said windows doen't run smoothly, always restart, a lot problem with hardware driver. So my question is that anyone have windows installed in mbp and have the same issue. I also heard that windows have problem with the apple new multi-touch trackpad. Your comment will be very much appreciated.
