As much as I think the 330 offers pretty good bang for the buck, you can get a better deal if you opt for the Lenovo 100E, a super cheap education-focused laptop designed in partnership with Microsoft. It's designed more for younger students, but if all you want is something for the classroom, the 100E might be smarter choice.
The next level up is the Ideapad 330S, where the S stands for slim. Sure enough, the 330S is basically the slimmer, sexier cousin of the 330. At 0.7-inch, it's pretty thin and the bezels are much narrower as well. The 330S weighs 3.5 pounds and up, which is a hair lighter than the 330. Instead of a plastic shell, the top of the 330S is clad in aluminum, giving it a much more sophisticated feel. It has the same ports as the 330 as well.
Starting at $500, the 330S comes in 14 and 15-inch configurations, with the option for full HD screens with IPS (in-plane switching). The keyboard is backlit, and there are a couple of powerful 2-watt stereo speakers, also with Dolby Audio support. I liked the feel of the keys here as well with a nice ergonomic travel, and the overall slimmer and chic design of the 330S felt a lot more grown up than the 330. And, just like the 330, you can equip the 330S with an 8th generation Intel Core i7 plus an NVIDIA GeForce GTX1050.
