UltrabookReview
Derek Sullivan | January 2023
"Compared to the previous year’s Inspiron, Dell upgraded the screen aspect ratio on this generation, but also transitioned to a more minimalistic centered keyboard flanked by up-firing speakers. The 16-inch screen is huge plus and I really appreciate the extra real estate without sacrificing the footprint much. This year’s model is a little larger than last, though, as the former model was already very small for a 15 incher."

Allen Ngo | October 2021
"The main selling point of the IdeaPad Slim 7i Pro versus a regular IdeaPad Slim 7 is its faster Core H-series CPU. In reality, the Core i7-11370H is only marginally faster than the U-series Core i7-1165G7 to the point where most users are not likely to notice the benefits. The slight performance uptick comes at the cost of slightly higher power consumption as well meaning owners will have to deal with potentially warmer temperatures or louder fans to compensate. Unless if you happen to be a power user, then the regular non-Pro model will be more than enough. Once you go 90 Hz, you can't go back."
