So, you’re ready to buy a new Windows computer to replace that old laptop you’ve been using for years — the one with the worn-out keyboard and cracked monitor — and you’re trying to figure out where to get it. The short answer: it depends. Do you prefer to try out keyboards before you buy? Do you like to peruse technology in a store dedicated to one brand, or compare various computers side by side? Or maybe you prefer to compare options online and build exactly what you want.
