Looking for a solid, no-frills 15.6" laptop for under $500? Lenovo's 15.6-inch Ideapad G550 is exactly what you need. While this notebook doesn't boast a lot of extras it still contains a dual core processor, 4GB of ram, and a DVD player. It's more than capable of handling basic computer functions and browsing the web. This is another laptop that doesn't offer a ton of portability (its battery only lasts about 4 hours), so it's great for lounging around the house. This laptop would also make a great second computer due to its ultra-low price tag.
