<p>Avoid Dell, shoddy customer service and overpriced upgrades. For psych, I’d recommend portability over power. If you’re PC, go for an Ultrabook. The new Ivy Bridge ones will most likely get extremely long battery life. Acer and Asus have some good ones out and on the way. And then there’s the Macbook Air or Pro, which are more powerful but leaps and bounds more expensive.</p>
