So you're buying a new computer? Well, you're in luck, because there's never been a better time. They are faster, smaller, and more powerful than ever before, and they don't necessarily have to cost you an arm and a leg (in fact, plenty of decent desktops and laptops can be had for less than $500). But should you get a Mac or a PC? Laptop or desktop ? Specs-wise, what difference does having an AMD or Intel processor make? And if you're planning on getting a laptop, how do you make sense of the alphabet soup that is Wi-Fi (802.11a, b, g, n)? We have a wide variety of computers here you can choose from and compare.
