>Are lithium ion batteries exclusive to Macbooks
They were for a long time in the wider retail market. Right now? I'm actually not entirely sure. Does the Dell XPS have a lithium ION battery? That's the only laptop competing with macbooks right now.
>plenty of laptops have rich colour IPS these days
None as good as apples macbooks. Dells 2017 XPS 4K display is not as good as a 2015 Macbook. For another comparrison. Lenovo thinkpad P51 display is not as good as the current apple iPad. That's a £1500 laptop

>Have you tried most windows laptops
Unironically yes. As I said before, both my job and most of my hobbies involve heavy computer use.
>also please explain in detail what you mean by "utilising RAM"
What do you plug your RAM into mate? That's right, a motherboard. What configures the RAM, mate? That's right, a CPU. Do you know what dual channelling is? Do you know what bottlenecking is? Do you know what the date is today? Do you know where you are?.
