Well i have tested W7 now for 6 month, and its WAY much better than Vista, but i dont know if its beets XP... I dont know, but im running it on DELL XPS M1330 and my fan is ON the whole time, With Vista the computer sucked, and when im installing XP on it, ITS ROCKN ROLL.... W7 here to stay? Dont think so, this is just a middle phase of microsoft i believe....( remember that this is my thoughts of W7, and only mine, copywri.... hehe
