I’m not going to lie. I was very skeptical when I bought this laptop because it wasn’t a brand I’d heard of before. I am so happy I did. That touch screen, while not something I use daily, is seamless. The display is beautiful. I like the size of the keys and my favorite aesthetic is the 10 key. It runs as fast as any comparable laptop but I felt I got a bigger screen and 10 key for cheaper than some of the more well known brands. I even bought a Lenovo desktop when I went back to school.

For the price that I got it for, this Lenovo laptop is a great deal. It has everything that I wanted, such as: touch screen LCD, HDMI 2.0 output, 8GB RAM, and it's a perfect sized laptop and beautiful brush metal design. I am very happy to get this! At first, I was worried that it had HDMI 1.4 because there were no details about what HDMI version it had. But luckily, it's at least HDMI 2.0 as tested on my LG CX OLED TV.

I purchased this laptop for $300. The kids use it for gaming and adults when certain tasks are easier on a PC than a Mac (certain websites just don't work on my Mac). I also wanted another machine to experiment with AI (Chat GPT, etc.) I am not comparing this to my Mac but to my work laptop which is an HP. Pros: - touch screen - large lapboard - great for big fingers and has a 10 key on the keyboard in addition to the numbers at the top - easy set-up - intuitive to use Cons: - very poor resolution (this makes me not want to use it more than necessary because I am concerned about eye strain) - pointer often does not work, which is ok because I can just touch the screen I can't compare this machine to others in the price range because I have not purchased a PC for personal use in over a decade. I would buy it again because it meets our needs at a very reasonable price point.
