When you're out to purchase a laptop, don't just pay attention to its hardware specs and connectivity features. Think about the following things as well that everyone's guilty of not paying enough attention to.
If you expect to type a lot on your laptop, make sure you visit an electronic store and try out its keyboard before purchasing it (online). Better safe than sorry, right?
Numpad is necessary for people dealing with a lot of numbers while they work on the laptop. A dedicated numpad will go a long way in making typing numbers a convenient exercise.
If you can't use an external mouse, pay close attention to a touchpad of the laptop before purchasing it. Textured touchpads are better than plain ones, isolated mouse buttons are generally better.
Remember that bigger is always better, in terms of battery, if you need greater battery life. Instead of 3-cell battery equipped laptops, try to buy 4-cell, 6-cell or 8-cell battery laptops.
Most laptops sport 1366x768 pixel resolution. While the Chromebook Pixel (pictured here) has 2560x1700 screen, you should aim to get at least a 1920x1080 pixel screen for watching movies like a boss.
If you're going to be video chatting a lot on your new laptop, make sure it has at least a 720p HD webcam built-in.
