Andreas Osthoff | July 2022
"The Apple MacBook Air M2 Entry is a very good, but too expensive daily MacBook. The new MacBook Air M2 is undoubtedly once again a very good mobile companion, but we are still a little bit disappointed on a very high level, which is definitely connected with the increased price point. The new chassis is extremely slim and the front edge is no problem during typing, but the bezels are pretty wide for a modern device and in addition with the vertical space required for the notch, the new Air has larger footprint than some Windows rivals."

Olivier Martin, Ryan Lim, and John Peroramas | April 2023
"The Dell G15 (2022) is a 15.6-inch budget gaming laptop, and is great for gaming. You can configure the laptop with powerful Intel 12th Gen. CPUs and various NVIDIA dedicated GPUs, all of which deliver a smooth gaming experience at 1080p. There's also a QHD 240Hz display option if you want better visuals, though you'll have to pair it with the top-end NVIDIA GeForce RTX 3070 Ti to get good frame rates. It doesn't get overly hot or loud under load, and there's no noticeable throttling on the CPU or GPU. Unfortunately, the 120Hz panel has a slow response time, causing noticeable ghosting, and it doesn't support variable refresh rate."
