Pros and Cons

Lenovo ThinkBook 15 Gen 4

Strengths

The Lenovo ThinkBook 15 Gen 4 has a sleek and powerful design that's perfect for professionals, students, and anyone who needs reliable performance.
It comes with impressive specs like an Intel Core i7 processor, 40GB of RAM, and a speedy 1TB SSD, making it ideal for demanding workloads.
The keyboard and trackpad feel very premium, with comfortable typing and a smooth, accurate touchpad experience.
The laptop has excellent connectivity options, including Thunderbolt 4, an Ethernet port, and Wi-Fi 6, ensuring stable internet connections.

Weaknesses

The display is not as color-accurate or vibrant as more expensive Ultrabooks, making it less ideal for professional photo or video editing.
The integrated graphics are sufficient only for everyday tasks and light gaming, but won't handle demanding 3D workloads or AAA games.
Battery life falls short of ultra-portables, lasting around 6 to 8 hours under normal use.
While portable, the laptop is still a 15.6-inch device, making it less suitable for frequent travelers who need an ultra-compact model.

Lenovo IdeaPad Slim 3

Strengths

A decent laptop with a clean, sleek design that looks similar to the MacBook Pro 14.
The color is quite similar to the MacBook Pro 14, and the rounded corner look kind of alike.
The overall build quality is just okay, but for a $700 US laptop, it's not bad at all.
The lid cover is made of aluminum, and the edges are nicely rounded, which is a great job by Lenovo.
The OLED panel has more vibrant colors, good clarity, and up to 400 nits of brightness.
Typing experience on this laptop feels good, with large key caps and a slight curve.
Multitasking is very comfortable, thanks to the Intel Core i5 13420H processor and 16 GB of memory.

Weaknesses

The chassis is made of plastic, which can feel cheap and flimsy.
There are leftover plastic bits along the edges, which detract from the overall build quality.
The keyboard doesn't feel solid like the aluminum one on higher-end models.
None of the connections support high-speed data transfer, as both USB-A and USB-C ports are limited to 5 GB/s.
The speaker volume is kind of low, even at full volume, making it difficult to hear in a small room.
The audio quality is average and sounds flat compared to other laptops.
Battery life is just about 4 hours and 30 minutes, which may not be sufficient for long trips or extended use.
